#beginner program
Before you start any program
Hypertrophy just means muscle growth. You'll find plenty of programs but first you must learn what really matters in a program. Read Hypertrophy Blueprint, it contains all the knowledge you need to grow muscles. After reading this, you'll be able to make changes to any program.
You can find many free programs on websites like LiftVault, BoostCamp or FitnessWiki
Are you a beginner?
When you're new to fitness, the best thing you can do is follow a program built by an experienced coach. It's tempting to try and design your own routine, but you're unlikely to come up with something more effective. A solid plan is much more than just a list of exercises; it’s a careful balance of volume, intensity, and smart progression that takes expertise to get right.
If you’re working out from home or have limited equipment, this free beginner program list is an excellent place to start. It’s flexible and offers options based on the gear you have, including a full bodyweight program if you have no equipment at all.
So, what kind of schedule works best for beginners? A full-body routine three times a week or an upper/lower split four times a week are your best bets. As a novice, you get better results by training each muscle group at least twice a week, which helps maximize your body's muscle-building response. This is supported by the study "Effects of resistance training frequency on measures of muscle hypertrophy, a systematic review and meta analysis" by Schoenfeld et al., published in Sports Medicine, 2019. This approach also lets you practice the main lifts more often to build a solid foundation. If you can train four days a week, an upper/lower split is a fantastic choice because it hits every muscle twice while giving you plenty of time to recover and grow.
Ready to hit a fully-equipped gym? Here are a few great starting points:

#boost neat One more thing: before you start any serious cardio, we recommend boosting your metabolism through NEAT (Non-Exercise Activity Thermogenesis). In simple terms, this just means getting more active in your daily life. Aim to increase your step count to 10,000, 15,000, or even 20,000 steps a day. A higher step count burns more calories and can accelerate your weight loss. You can find helpful strategies for this in our Step Count Progression guide.

AI Fitness Advice (ChatGPT, Gemini, Claude)
AI gets its training data by scraping vast corners of the internet, including forums like Reddit where bro-science, myths, and misinformation spread easily. Because of this, AI-generated workout routines and diet plans often sound incredibly convincing, even when they are deeply flawed or just generic templates. Interestingly, AI tends to perform best in fields where the work is highly verifiable. In software engineering or mathematics, you can test an output instantly and cheaply. Code either compiles and passes its tests, or it fails. A math proof is either right or wrong. The feedback loop is immediate. Fitness and nutrition do not work that way. There is no quick, objective validation system. If an AI gives you a subpar training program, you might not notice the issues for weeks or months. Even then, pinpointing the cause is incredibly difficult. Real-world progress depends on a complex web of individual variables, including your genetics, adherence, recovery, sleep, stress, exercise technique, and daily nutrition. Right now, AI is most effective in fitness when it is paired with an experienced human who can critically evaluate and tweak the output. Unlike writing code, fitness does not have an automated compiler to instantly flag a bad hypertrophy block or a useless dieting strategy.

Why read this Guide?
These guides might look intimidatingly long and detailed, but in our coaching practice, we get clients up and running with these exact fundamentals in their very first week. Usually, within 2-5 weeks, they are already seeing the scale move in the right direction. It really is as straightforward as downloading MacroCodex and taking action.
We have packed these pages with the kind of hands-on intuition, troubleshooting techniques, and myth-busting that normally takes a coach five to ten years of trial and error to figure out.
Most beginners spend their first year or two spinning their wheels because they have no idea how to eat. They obsess over perfecting their training routine, even though they could just grab a free, proven program from LiftVault, FitnessWiki, or Boostcamp and get great results. Training is actually the easy part. If you are doing about ten challenging sets per muscle group each week (around zero to three repetitions in reserve) and gradually adding weight or reps, you will grow.
We focus purely on the high-leverage basics. You can find endless "science-based" optimizations online, but almost all of them offer microscopic returns. This guide prioritizes the vital 20% of effort that yields 80% of your real-world results.
When you first start lifting, you can get away with a terrible diet because "newbie gains" carry you through. Eventually, though, you will hit a wall. Even if you manage to build some decent muscle by accidentally eating enough protein and calories, that new muscle often ends up buried under a layer of stubborn body fat. The result is a physique that looks disappointing in the mirror, despite all your hard work in the gym.
Reading this can save you years of frustration. By the end, you will understand nutrition the exact same way elite performers do, including IFBB pros, athletes, models, and Hollywood actors.
Let's establish a ground rule.
You are not allowed to say "my diet is fine" unless you can fill in these blanks on the spot:
"My maintenance is X calories. My goal is Y, so I am eating at a Z calorie deficit or surplus. This means my daily target is A calories, made up of B grams of protein, C grams of carbs, and D grams of fat."
Without these numbers, "eating clean" usually just means eating home-cooked, whole foods without any actual awareness of your energy intake. If you want predictable, repeatable progress, guessing is not enough. You need the actual data. This guide walks you through exactly how to find and track those targets.
If you ask any top-tier athlete, fitness model, or actor about their nutrition, they can instantly tell you their maintenance calories and daily targets.
Whether you want to build a lean, athletic frame or the mass of a competitive bodybuilder, your results depend entirely on these core principles. Knowing them is what separates people who feel lost from those who make steady, visible progress week after week. It ensures your hard work in the gym actually pays off. Ultimately, it comes down to managing three variables: the fuel you put in your body (calories and macros), your total mass (your scale weight), and your body composition (your body fat percentage).
What the Scale Doesn't Tell You
Track Your Weight Trend, Not Your Daily Weight
Stepping on the scale every morning can be incredibly frustrating, mostly because our weight naturally bounces around. It's completely normal for your weight to shift over the course of a single day or week simply because of water retention, recent meals, and glycogen levels. Instead of stressing over those daily ups and downs, it's much more helpful to look at the overall trend over several weeks.
Why bodyfat% matters?
Staring at the scale and obsessing over a single number is an easy trap to fall into, but that weight doesn't tell the whole story. Your body is far more than just a single lump of mass. Instead, it is split into two main parts: fat mass and lean mass. Fat mass is pretty self-explanatory, while lean mass is everything else, including your muscles, bones, organs, and water weight.
Tracking both your total weight and your body fat percentage reveals the actual ratio between these two components. This gives you a much clearer understanding of your true baseline and lets you accurately measure the quality of your progress over time.
Take a look at the image below. Both men stand at 180 cm (5'11") and weigh 80 kg (176 lbs). Despite sharing identical stats, one looks soft and out of shape, while the other looks lean and athletic. The deciding factor here is their body fat percentage.
Man 1 carries a higher body fat percentage of 30%. This means 30% of his total weight comes from fat, leaving the remaining 70% as lean mass.
Man 2 sits at a much lower body fat percentage of 10%. Only 10% of his weight is fat, while a massive 90% is lean mass.
These numbers make their physical differences immediately obvious. For Man 1 to build a leaner, more athletic build, he needs to focus on dropping fat while packing on lean mass.
True body transformation isn't just about moving the scale up or down. It's about shifting your overall body composition to find the right balance between fat and lean tissue.
Look at it this way. If someone called you and only shared their height and weight, you would have almost no idea what they actually looked like in person. But if they added their body fat percentage to the mix, you'd immediately have a highly accurate mental picture of their build.
The Problem with Most Body Fat Measurements
Since your body fat percentage is such a critical metric, you need an accurate way to measure it. The truth is, most methods are wildly inconsistent.
Smart Scales and Smartwatches
Just a quick heads-up: don't rely too heavily on consumer-grade smartwatches and scales. They're incredibly convenient, sure, but their body fat estimates are notoriously off. Basing your fitness decisions on these numbers can easily steer you in the wrong direction. There's a reason clinical equipment costs thousands of dollars. You simply can't squeeze that level of technology into a gadget that costs less than a grand.
Finding a proper scan is actually pretty straightforward. If you search for "DEXA scan near me", you'll likely find a local clinic or gym offering them for a reasonable fee. I'd recommend calling ahead to confirm the pricing first, since different facilities can charge wildly different rates for the exact same scan. Make sure to specifically ask for a "Body Composition DEXA scan." If you plan on tracking your progress over time, try negotiating a package deal for a few scans throughout the year. Many providers are happy to offer a discount if you prepay or commit to a bundle.
InBody
You've probably seen InBody machines at your local gym, as they've become incredibly common worldwide. The models you'll run into most often are the InBody 260 and 270. While these are perfectly fine for keeping an eye on overall trends (like whether your muscle or fat mass is generally going up or down), they aren't highly accurate. In fact, they aren't even close to the precision you get from a DEXA scan.
| Feature | InBody 260/270 | InBody 770 | InBody 970/970S |
|---|---|---|---|
| Frequencies | 2 (20, 100 kHz) | 6 (1, 5, 50, 250, 500, 1000 kHz) | 6 or 8 depending on model/region (up to 3 MHz) |
| Segmental analysis | ✓ | ✓ | ✓ |
| Intracellular vs extracellular water | Basic | Advanced | Most advanced |
| Phase angle | Limited | ✓ | Multi-frequency segmental phase angle |
| BIVA/Cole-Cole analysis | No | Limited | ✓ |
| Target users | Gyms | Sports medicine, clinics | Research, hospitals |
As you go up the product line, the accuracy gets better:
InBody 970/970S > InBody 770 > InBody 260/270
Yet, even the top-of-the-line InBody 970/970S falls short of a DEXA scan when it comes to pinpointing body composition. The high-end models do a much better job of minimizing errors and delivering deeper metrics, but as the table shows, they still can't match DEXA's gold standard accuracy. Since these professional machines cost thousands of dollars and still have limits, a cheap smart scale doesn't stand a chance. Save your money instead of wasting it on those home gadgets.
Accuracy of methods
For body fat % measurement, in terms of accuracy:
| Tier | Category | Methods | Notes |
|---|---|---|---|
| Tier 1 | Criterion & Reference Methods | MRI | Direct adipose tissue quantification, no assumptions |
| Tier 1 | Criterion & Reference Methods | 4-Compartment Models (4C) | Criterion gold standard for living subjects |
| Tier 1 | Criterion & Reference Methods | DEXA | 3-compartment model, high precision, clinical reference |
| Tier 2 | High-Quality Densitometry | Hydrostatic Weighing (UWW) | Classic 2-compartment density method |
| Tier 2 | High-Quality Densitometry | Bod Pod | Air displacement plethysmography, comparable to UWW |
| Tier 3 | Validated Field & Clinical Methods | Ultrasound (B-mode / A-mode) | Measures fat layer thickness; less operator-dependent than calipers |
| Tier 3 | Validated Field & Clinical Methods | Expert Skinfold Calipers | Highly dependent on technician skill; uses validated equations |
| Tier 3 | Validated Field & Clinical Methods | High-End Multi-Frequency Segmental BIA (e.g., InBody 970/770) | ≥6 frequencies, up to 1 MHz, 8-point electrodes |
| Tier 4 | Good Multi-Frequency BIA (Research/Clinical Grade) | Other MF-BIA devices (e.g., Seca mBCA, Tanita MC-780) | Reasonable accuracy; typical error ~3.5–5% vs DEXA (varies by population) |
| Tier 5 | Estimation & Basic Devices | US Navy Formula | Circumference-based; population averages; error typically >4–5% |
| Tier 5 | Estimation & Basic Devices | Single-Frequency BIA | Consumer devices; highly hydration-dependent; lowest electronic accuracy |
Visual guide
Visual estimates, even by professionals, are significantly less accurate than DEXA scans, no matter what some forum discussions might claim. That said, for contest or photoshoot preparation, visual assessments for conditioning are a practical method. In such cases, it's beneficial to seek guidance from a coach's trained eye for a more reliable evaluation.
Why are visual body fat comparisons so often misleading?
A few major factors explain why looking at photos rarely tells the whole story.
1. The same body fat percentage can look completely different, even at the exact same height
Body fat percentage only tells you the ratio of fat to your overall body weight. It does not reveal how much muscle you carry unless you factor in your scale weight to calculate your actual lean and fat mass.
Take two men who are both 180 cm (5 ft 11 in) tall and sit at 10% body fat:
- One weighs 70 kg (154 lb)
- The other weighs 90 kg (198 lb)
Even with identical body fat percentages, their physiques will not look similar at all.
The 90 kg individual has significantly more lean mass, along with more absolute fat mass.
- The 90 kg person has 9 kg of fat and 81 kg of lean mass.
- The 70 kg person has 7 kg of fat and 63 kg of lean mass.
This means the heavier man has 2 kg more fat, but a massive 18 kg more lean mass. That extra muscle creates a larger, rounder, and much fuller shape. Because of this, the heavier man will usually look leaner and more defined, despite both individuals sitting at exactly 10% body fat.
With 18 kg of extra muscle, his biceps, quads, and lats have a much larger circumference. This gives him a naturally wider and more developed silhouette.
2. The "peaks and valleys" effect of body topography
Most people can guess body fat fairly well if the subject has decent muscle mass. However, those guesses get highly inaccurate when looking at someone with average or below-average muscle.
It sounds counterintuitive, but visual leanness depends heavily on your body's physical contours, not just how thick your fat layer is. The 90 kg lifter has prominent muscle peaks. When a bicep flexes and peaks, it stretches the skin and subcutaneous fat thin over the top. At the same time, the valleys between muscles (such as the gap separating the bicep and tricep) run deeper because the muscles on either side bulge outward. This casting of deep shadows and sharp transitions creates a highly defined look.
The 70 kg man has smaller muscle bellies. While he carries 2 kg less total fat, that fat is spread over a smaller frame. The skin does not stretch as tightly over his muscles, which leaves him with softer transitions and less defined separation.
This dynamic only holds true if both people are roughly the same height. It explains why a simple body fat percentage can never fully describe how someone actually looks.
Fitness influencers frequently exploit this topographic effect to look much larger on screen than they are in person.
You might wonder how someone of your exact height and weight looks so much bigger. The secret is usually a lower body fat percentage. A leaner build creates deeper shadows and sharper muscle separation, making muscles pop on camera.
If you saw that same influencer standing next to an average person, you would instantly see their true size. Often, they are not actually massive; they are just incredibly lean, and the lens exaggerates their shape.
This also explains why heavy strongmen or powerlifters can look surprisingly lean, sometimes even showing visible abs, at higher body fat percentages. Their massive amount of lean muscle mass carries the weight differently.
This does not mean tracking body fat is useless. If you know someone's height, weight, and body fat percentage, you can get a very solid mental picture of their build.
3. Fat distribution is highly individual
When we try to guess body fat, we usually focus on obvious areas like the shoulders, arms, chest, waist, and abs. We look at the core and the limbs because those are the areas on display.
But fat does not accumulate evenly. One person might store fat primarily in their thighs, hips, glutes, or lower back, while another stores it mostly around their stomach.
A DEXA scan measures fat distribution across your entire body to find your true overall percentage. Visual guesses, on the other hand, rely on just a few visible areas. Since everyone stores fat differently, two people with identical body fat levels can look entirely different.
Coaches frequently rely on calipers or DEXA scans to track progress, but when bodybuilders step on stage, they are judged strictly on visual conditioning. Precise body fat percentages simply do not enter the equation. Many trainers love to say the eyes are the ultimate judge, but human vision still cannot match the precision of an MRI or a DEXA scan.
Long before these high-tech tools became common, lifters used a much simpler rule of thumb: bulk until your abs fade, then cut until they show up again. You do not need cutting-edge technology to get results.
If you cannot get a DEXA scan, the free MacroCodex app has a built-in US Navy body fat calculator. The classic formula it uses is more than enough to establish a solid baseline.
| Category | Male Body Fat % | Female Body Fat % |
|---|---|---|
| Essential Fat | 2–5% | 10–13% |
| Athletic | 6–13% | 14–20% |
| Fitness | 14–17% | 21–24% |
| Average | 18–24% | 25–31% |
| Obese | 25%+ | 32%+ |
Table source: American Council on Exercise (ACE). ACE Personal Trainer Manual (multiple editions), based on body fat classification ranges derived from: Heyward, V. H. Advanced Fitness Assessment and Exercise Prescription. Human Kinetics.
To translate male body fat targets to female equivalents, you can generally just add 9 to 10 percentage points.
Here is how that looks in practice:
- If the recommendation for a man is to cut to 10-12%, the target for a woman is about 19-21%.
- If a man is advised to bulk up to 17%, the equivalent target for a woman is roughly 26-27%.
This quick adjustment makes it easy to convert standard fitness guidelines between genders.
What's the Goal?
Your objective will dictate your entire approach, so it’s crucial to know exactly what you’re aiming for.
- Cutting is all about lowering your body fat while performing minimum required lifting to maintain existing muscle mass
- Body Recomposition is the process of building muscle and losing fat at the same time.
- A Lean Bulk focuses on maximizing muscle gain while accepting a minimal, controlled increase in body fat.
- An Underweight Bulk is a more aggressive approach for those who need to gain weight to reach a healthy range.
Manage expecations
A common trap for beginners is trying to chase multiple goals at the same time. Pros do not do this. They focus on one specific goal per phase.
When you are in a cutting phase to lose weight, building muscle shouldn't be your main expectation. While you can technically build muscle in a calorie deficit, the process is incredibly slow and tedious. It is like swimming against a strong current: you might make forward progress, but it takes an exhausting amount of effort.
In fact, once your daily calorie deficit goes past 400 calories, your rate of muscle growth drops off a cliff. Why waste energy stressing over muscle gains during a cut?
Real muscle growth is maximized when you are eating in a slight calorie surplus. If you want to dive deeper into the science behind this, check out this guide on why a surplus is prescribed when muscle can grow at maintenance.
A smarter strategy while cutting is to do an hour to an hour and a half of Zone 2 cardio every day. To keep your joints healthy and avoid overuse injuries, mix things up by rotating through brisk walking, incline treadmill walks, cycling, or swimming. To keep the muscle you already have, you only need to lift weights once or twice a week.
Once you successfully lean down, transition into a lean bulk. At this point, bump your lifting sessions up to three or four times a week and scale your cardio back to about 30 minutes. The calorie surplus from your lean bulk will act like fuel, allowing you to build muscle much faster.
Having those extra calories simply makes the entire muscle-building process much easier.
While burning fat is relatively straightforward when you put in the hours of low-intensity Zone 2 cardio, trying to pack on size while dieting is a tough battle.
Do not fight against basic calorie math or you will quickly burn yourself out. Use a surplus to build mass and a deficit to lose fat. It is that simple.
Why not just eat at maintenance and skip bulking or cutting altogether?
If you want a more detailed breakdown of this debate, take a look at this article explaining why a surplus is prescribed when muscle can grow at maintenance, and why we lean bulk or cut.
When you gain weight, it is always going to be a mix of muscle and fat. The goal of a lean bulk is to tilt those scales, maximizing muscle growth while keeping fat gain to an absolute minimum.
Eventually, you will need to run a cut to strip away whatever unwanted fat accumulated during your bulk. But do not worry, if you execute your lean bulk properly, the rate of fat gain is incredibly slow.
Fueling the Machine: Calories and Macros
Your body's transformation is fueled by what you eat. Calories are simply energy, eat more than you burn, and you’ll gain weight; eat less, and you’ll lose it. But the type of calories you eat determines the quality of that change. These are your macros:
- Protein is the brick and mortar for building muscle. Without enough of it, your body simply can't repair and grow, no matter how hard you train.
- Fats are non-negotiable. Healthy fats are essential for regulating the hormones that drive muscle growth and recovery, not to mention keeping your joints healthy. Skimping on them will sabotage your progress.
- Carbohydrates are your body's go-to energy source, especially for powering you through high-intensity workouts.
Workout does not build muscle.
Workout triggers a process which builds muscle using supplies from diet.
A person working out consistently triggers this BUILD process, but if the diet is not on point, this process halts prematurely and doesn't build anything.
The supplies are fats, carbs, and proteins, which all add up to total calories.
These are needed in the right proportion for growth; too low fat = hormones not working optimally, not enough joint lubrication, too low carbs = not enough performance, glycogen stores to fuel the workout, too low proteins = not enough building blocks for muscle, too low calories (coupled with low bodyfat% which is body's energy reserve) = not enough energy to sustain muscle protein synthesis.
The "Dieting Tips" Fallacy
"Just eat smaller portions" is advice we hear all the time. But without tracking your calories, you are basically guessing which parts of your meals actually need to shrink.
For instance, your diet might benefit most from cutting back on fats, but you decide to slash carbs or protein instead. You could end up hurting your gym performance, slowing down your recovery, or stalling muscle growth, all while making barely any progress.
Tracking your food solves this issue by showing you exactly where your calories come from. It takes the guesswork out of the process, allowing you to make targeted adjustments instead of cutting out the wrong things.
Many people assume that counting calories is incredibly restrictive. In reality, it usually gives you more freedom. Once you know your daily target, you can easily fit in the foods you love while still moving toward your goal.
The same goes for the classic "just cut carbs" advice. Every gram of stored carbohydrates (glycogen) holds onto several grams of water; the clue is right there in the word "hydrate." When you drop your carbs, your body quickly sheds that stored water. It is why beginners see the scale plunge in the first few days and assume they have lost a ton of fat, when it is really just water weight.
Without accurate tracking, it is easy to mistake water loss for fat loss, or to make dietary changes that do not actually address the root of the problem.
Measure, adjust, measure, and repeat.
Automation
While this guide walks you through how to calculate and track your metrics manually, doing it by hand isn't for everyone. If you prefer to automate the heavy lifting, you can use MacroCodex. It is a completely free app designed specifically around the exact methods we cover here, and it takes care of almost all the tedious math and daily tracking for you.
It is still worth reading through this guide to understand the logic behind the numbers. However, the app is a great shortcut if you are short on time, prefer a hands-on learning approach, or simply want a faster, more consistent daily routine.
The green dashed line represents your Total Daily Energy Expenditure (TDEE), which is your maintenance level. To drop weight, you will want to eat below this line to create a deficit. To pack on size, eat above it for a surplus. If your goal is body recomposition, aiming right around that line is your best bet.
More than 16,000 people are already using the tool. Get free MacroCodex app here
Setting it up is simple. Just log your daily calories and weekly weight, then choose your specific goal, whether that is weight loss, cutting, body recomposition, or a lean bulk. As your metabolism shifts and your actual TDEE changes, the app automatically adjusts your daily calorie and macronutrient targets so you do not have to recalculate everything yourself.

#exercise selection Does your routine include both compound and isolation exercises for every muscle? A 2019 study from Schoenfeld et al. confirms that this combination is crucial for ensuring full muscle activation and balanced development.
Limit to 1-3 exercises/muscle (mid-range compound + stretch + contracted, e.g., bench + pec deck + cable flyes). Strict form ensures tension on target muscles—cue mind-muscle connection (e.g., "pull humerus across body" on bench).
Heavy compounds first (e.g., deadlifts for back size); minor form loosening only on final reps if it keeps tension. No cheating that shifts load elsewhere.
See: Muscle Explorer for high quality Exercises.
#progression
To build muscle over the long haul, you have to find ways to do a little more over time. Whether that means adding weight, squeezing out more reps, or throwing in extra sets, keeping a weekly log of your progress is the only way to guarantee you are actually moving forward. Real growth happens when you get stronger in those moderate rep ranges. Think of it this way: if you start out benching 50 kg for 10 reps, and by the end of the year you are benching 100 kg for those same 10 reps, your chest is going to be significantly bigger. On the flip side, if you are benching 20 kg for 10 reps today and you are still doing the exact same 20 kg for 10 reps next year, you haven't actually progressed. You might have leaned out a bit and noticed some new definition, but you won't have built any new muscle mass. So, when should you actually add weight or reps? Should it happen every workout, every week, or once a month? The truth is, you don't need to force progress every single week. You should only increase the load or the reps when the current weight starts feeling comfortable and no longer gives your muscles a reason to grow. That comfort is just a sign that your body has adapted. Let's look at a quick example. Imagine you are benching 60 kg for a target range of 6 to 10 reps, leaving about 2 reps in the tank (which is 2 reps shy of failure, or 2 RIR) on each set. As your body adapts over time, that 60 kg is going to feel lighter. Eventually, you will hit 10 reps and realize you actually had 4 reps left in the tank (4 RIR). At this point, the set is no longer challenging enough to trigger growth, since the general rule is to stay within 0 to 3 reps of failure. Because you have already hit the ceiling of your 10-rep target, you can't just keep adding reps. Instead, you need to bump up the weight to bring that intensity back. However, if you were only doing 9 reps at that easier effort, your immediate move would be to add one more rep to hit your target of 10. This approach is called double progression: you focus on adding reps until you hit the top of your target range, and only then do you increase the weight once the current load stops challenging you. As you get more experienced and stronger, these weight jumps might only happen every few weeks or even months. That is completely normal. The main objective is to gradually build strength in those moderate rep ranges, and the muscle growth will follow naturally.
- Linear Progression (Gradual Increase)
How It Works: Add small, consistent increments to your weight or reps every workout or every week.
Example: If you're bench pressing 100 lbs for 3 sets of 8 reps, aim to increase the weight by 2.5–5 lbs every week, or add 1–2 reps per set.
- Double Progression (Weight and Reps Combo)
How It Works: Focus on achieving a specific rep range before increasing the weight. Once you can perform the target rep range (e.g., 8-12 reps) with good form, increase the weight and drop back to the lower end of the rep range.
Example: If your goal is to do 8–12 reps for squats, you'll first work on increasing your reps within that range. Once you can do 12 reps comfortably, increase the weight and go back to 8 reps.
Double progression is pretty easy to understand, so that's what you should use to progress in strength.

Strength Progression
You won't be able to measure weekly progress, 2mm added to muscle thickness is pretty hard to measure with a tape. The best proxy for muscle gain is if you're getting progressively stronger in the medium rep range (8-15). If you started by doing 10 reps of 50kg, and by the end of the year you can do 10 reps of 100kg, your muscle size has definitely increased. You've undeniably added muscle -

#recompdetail
Body recomposition tends to work best at around 15-25% body fat for men and 24-34% for women.
If you are a man with 25% to 30% body fat, cutting is usually the better option. You can still recomp at that level, but fat loss is usually slower than it would be with a proper cut.
At higher bodyfat% it's not that Recomp stops working but the fat loss rate is so slow, many newbies will become hopeless after not seeing any visual changes for months.
And if you are underweight or lean than 14% for male or 23% for female then there isn't fat store to fuel muscle building, muscle will still grow but since the stored energy reserve is low, it will be much much slower.
So if you are underweight or very lean or have a lot of bodyfat or training for a while (intermediate) or are after faster visual changes then Lean bulk and cut are better options for you.
When Recomp Makes Sense
Recomping can be a good option if you are:
- A complete beginner
- New to training or dieting
- Coming back after a long break
- Been sedentary for a while
- skinny fat, not visibly fat
- not underweight or very lean
- normal BMI between 19-24 but belly fat, love handles etc...
In most cases, it makes sense to recomp for the first few months, as long as you are not already underweight or very lean, such as at or below 10% to 13% body fat for men and at or below 19% to 21% for women.
If you are thin overall but still carry fat in places like your belly, face, thighs, or hips, you are probably dealing with the classic "skinny fat" look. In many cases, that means your body fat is closer to 20% for males and 29% for females.
Why Recomp?
When you recomp for the first few months, you eat at maintenance calories (TDEE). That is usually much easier to stick to than a surplus or deficit.
You also become more active gradually if you add Zone 2 cardio.
At the same time, you are adjusting to a new routine, learning to track calories, understanding maintenance calories and macros, and practicing progressive overload.
There is already a lot to juggle, and cutting or lean bulking can make things even more complicated.
Another benefit is that beginners can often build muscle during recomp and benefit from newbie gains. So even if cutting is eventually the better long-term choice, recomping may still add a few kilograms of muscle, which can raise your resting metabolic rate and make future fat loss easier.
It can also improve your stress tolerance and help your body adapt better to training and daily life.
Recomp is a good starting point for a proper lean bulk or cut later on.
What To Expect
Do not expect dramatic visual changes from recomp. Most of the progress is subtle, and beginners may not notice much visually even when things are improving.
Simple Rule
If you are obese, you can usually go straight into a cut.
If you want to ease into a new routine, recomping for a few months is a perfectly valid choice, even if progress is slower.
Why Most People Burn Out
Most people try to go from:
Overweight/Obese → Lean and Muscular
in a single step.
They hear things like:
“You can lose fat and build muscle at the same time.”
Yes, body recomposition is possible.
But just because something is possible does not mean it is the best approach for most people.
It is also possible to walk 100 km in a day. Most people either cannot do it or would burn out trying.
The same thing happens with fitness.
People try to:
- learn calorie tracking
- lift weights
- stay in a calorie deficit
- do lots of cardio
- optimize macros
all at the same time.
That is why many beginners quit.
Instead, break the process into stages.
The Better Approach
Stage 1 — Recomp Phase
Overweight/Obese → Recomp for a few months
Goal:
- Learn the basics
- Build consistency
- Capture easy newbie muscle gains
During this stage, eat around maintenance calories while lifting weights consistently.
Why this works:
1. You learn the fundamentals
You learn:
- calorie tracking
- maintenance calories
- protein intake
- meal structure
- workout consistency
Without the stress of an aggressive cut.
2. You capture beginner gains
New lifters can build muscle relatively quickly.
More muscle means:
- higher daily energy expenditure
- better body composition
- improved strength
- better workout performance
3. It is easier mentally
Adding a large calorie deficit and lots of cardio immediately can feel overwhelming.
Recomp lets you build habits first before increasing difficulty.
Stage 2 — Proper Cut
Now you already know:
- how to track calories
- how maintenance feels
- how to lift consistently
The only new skill is learning how to sustain a calorie deficit.
This is where you:
- add moderate Zone 2 cardio
- reduce calories gradually
- focus on fat loss while maintaining muscle
Because the foundation is already built, the cut feels much easier.
Stage 3 — Lean Bulk
Lean → Controlled Surplus
At this point:
- insulin sensitivity is usually improved
- appetite regulation is better
- training performance is higher
- you are lean enough to actually see muscle gain clearly
Now you enter a small calorie surplus and focus on building muscle.
This is where muscle building becomes much more productive and enjoyable.
You can train 3–4 times per week consistently and make excellent progress.
Stage 4 — Final Cut
After months of lean bulking, you cut again.
This time, when body fat gets low:
- muscle definition becomes visible
- shoulders, arms, chest, abs, and legs start standing out clearly
This is the stage where people achieve the “lean and muscular” look they originally wanted.
Important Notes
- Recomping is great for beginners, but it is not magic.
- For overweight/obese people, getting truly lean through recomp alone can take a very long time, year+
- Spending 12+ months trying to recomp is usually inefficient.
For most people:
- 2–3 months of recomp is enough
- Busy people can stretch it to 4–5 months
After that, a proper cut is usually the better option.
A good sign you are ready for your first cut is when:
- calorie tracking feels normal
- lifting is part of your routine
- you understand your maintenance calories
- you feel consistent instead of overwhelmed
That is when you level up to the next stage.
#workout-frequency
How often should you lift weights?
-
Recomp: 3–4x/week If you're new, detrained, a beginner, or returning after time off, you can usually recover well from 3–4 sessions per week while still building muscle and losing fat. You are handling easy weights here, so recovery isn't much of an issue.
-
Lean bulk: 3–4x/week You are in a calorie surplus and lean enough to prioritize muscle growth. Muscle gain is generally maximized in a surplus, so training performance and recovery are better.
-
Cut / weight loss: 1–2x/week In a calorie deficit, recovery and muscle growth potential drop. Once the deficit becomes large (around 400+ kcal/day), muscle gain slows significantly, so the goal shifts more toward maintaining muscle rather than maximizing growth.
-
Maintenance: 1–2x/week Maintaining muscle requires far less training volume than building it. A small amount of hard training is often enough to keep most of your muscle and strength.
-
PED users: 5–6x/week PEDs can dramatically increase recovery, work capacity, and protein synthesis, allowing much higher training frequency and volume. PED users can build muscles much faster than naturals even in deficit.
#cardio-frequency
To find your zone2, checkout this Zone2 Guide
How often should you do cardio?
Zone 2 is low-intensity cardio, so it can be sustained for much longer than high-intensity cardio like sprints, allowing for a higher cumulative calorie burn over time.
-
Recomp: ~50-60 minutes/day of Zone 2 cardio Helps increase TDEE and makes it easier to stay in a slight deficit while still recovering well enough to build or maintain muscle. Deficit = TDEE − calorie intake.
-
Lean bulk: 30–40 minutes/day of Zone 2 cardio Your main goal is muscle gain, not maximizing calorie burn. Moderate cardio helps with cardiovascular health, work capacity, recovery, and appetite without interfering too much with gaining weight.
-
Cut / weight loss: 1–2 hours/day of Zone 2 cardio More Zone 2 cardio increases calorie expenditure, helping create larger deficits for faster fat loss. Since lifting frequency is lower during this phase, more time and recovery capacity can be allocated toward cardio. Since you are performing relatively high amount of cardio, vary it between bicycling, fast walking, incline walking, swimming to avoid overuse injuries.
-
Maintenance: 30–40 minutes/day Enough to maintain cardiovascular fitness, general health, and keep TDEE above a sedentary level without creating excessive fatigue or energy demands.
Since Zone 2 cardio is low intensity and relatively easy to recover from, it usually does not interfere much with recovery from lifting weights.
You can separate the sessions across the day, such as doing cardio in the morning and lifting in the evening, or the other way around.
- Use cardio as a tool to increase energy expenditure, not to replace a calorie controlled diet
- High intensity cardio can interfere with strength training recovery
Note: Cardio increases your Total Daily Energy Expenditure (TDEE), thereby increasing your calorie deficit and accelerating fat loss.
It also helps break plateaus by maintaining high energy demands, forcing the body to tap into fat reserves to meet those needs.
#diet-tips "Just eat smaller portions" is advice we hear all the time. But without tracking your calories, you are basically guessing which parts of your meals actually need to shrink.
For instance, your diet might benefit most from cutting back on fats, but you decide to slash carbs or protein instead. You could end up hurting your gym performance, slowing down your recovery, or stalling muscle growth, all while making barely any progress.
Tracking your food solves this issue by showing you exactly where your calories come from. It takes the guesswork out of the process, allowing you to make targeted adjustments instead of cutting out the wrong things.
Many people assume that counting calories is incredibly restrictive. In reality, it usually gives you more freedom. Once you know your daily target, you can easily fit in the foods you love while still moving toward your goal.
The same goes for the classic "just cut carbs" advice. Every gram of stored carbohydrates (glycogen) holds onto several grams of water; the clue is right there in the word "hydrate." When you drop your carbs, your body quickly sheds that stored water. It is why beginners see the scale plunge in the first few days and assume they have lost a ton of fat, when it is really just water weight.
Without accurate tracking, it is easy to mistake water loss for fat loss, or to make dietary changes that do not actually address the root of the problem.
Measure, adjust, measure, and repeat.
#why-cardio
Why do Zone2 cardio?
A calorie deficit is:
Deficit = TDEE (Maintenance Calories) - Intake
Most people focus only on lowering calorie intake, but increasing energy expenditure is another way to create the same deficit.
Example:
For many people, eating only 1,500 kcal is difficult and may leave them hungry, tired, and less active.
Instead, they could increase their activity through easy Zone 2 cardio such as brisk walking or incline walking:
The deficit is exactly the same, but the person gets to eat 500 more calories per day.
This is important because sedentary people already have relatively low energy expenditure. If they rely entirely on food restriction, they often become hungry, lethargic, and unconsciously move less throughout the day. As body weight decreases, energy expenditure also naturally falls. Together, these effects can reduce TDEE and slow fat loss.
Easy Zone 2 cardio helps counter this by increasing daily energy expenditure while being relatively easy to recover from. This allows many people to maintain a meaningful calorie deficit while eating more food, feeling better, and staying more active throughout the diet.
The goal is not simply to eat as little as possible. The goal is to create a sustainable calorie deficit while keeping energy expenditure as high as reasonably possible.
#bodyfatmeasurement
Smart Scales and Smartwatches
Just a quick heads-up: don't rely too heavily on consumer-grade smartwatches and scales. They're incredibly convenient, sure, but their body fat estimates are notoriously off. Basing your fitness decisions on these numbers can easily steer you in the wrong direction. There's a reason clinical equipment costs thousands of dollars. You simply can't squeeze that level of technology into a gadget that costs less than a grand.
Finding a proper scan is actually pretty straightforward. If you search for "DEXA scan near me", you'll likely find a local clinic or gym offering them for a reasonable fee. I'd recommend calling ahead to confirm the pricing first, since different facilities can charge wildly different rates for the exact same scan. Make sure to specifically ask for a "Body Composition DEXA scan." If you plan on tracking your progress over time, try negotiating a package deal for a few scans throughout the year. Many providers are happy to offer a discount if you prepay or commit to a bundle.
InBody
You've probably seen InBody machines at your local gym, as they've become incredibly common worldwide. The models you'll run into most often are the InBody 260 and 270. While these are perfectly fine for keeping an eye on overall trends (like whether your muscle or fat mass is generally going up or down), they aren't highly accurate. In fact, they aren't even close to the precision you get from a DEXA scan.
| Feature | InBody 260/270 | InBody 770 | InBody 970/970S |
|---|---|---|---|
| Frequencies | 2 (20, 100 kHz) | 6 (1, 5, 50, 250, 500, 1000 kHz) | 6 or 8 depending on model/region (up to 3 MHz) |
| Segmental analysis | ✓ | ✓ | ✓ |
| Intracellular vs extracellular water | Basic | Advanced | Most advanced |
| Phase angle | Limited | ✓ | Multi-frequency segmental phase angle |
| BIVA/Cole-Cole analysis | No | Limited | ✓ |
| Target users | Gyms | Sports medicine, clinics | Research, hospitals |
As you go up the product line, the accuracy gets better:
InBody 970/970S > InBody 770 > InBody 260/270
Yet, even the top-of-the-line InBody 970/970S falls short of a DEXA scan when it comes to pinpointing body composition. The high-end models do a much better job of minimizing errors and delivering deeper metrics, but as the table shows, they still can't match DEXA's gold standard accuracy. Since these professional machines cost thousands of dollars and still have limits, a cheap smart scale doesn't stand a chance. Save your money instead of wasting it on those home gadgets.
Accuracy of methods
For body fat % measurement, in terms of accuracy:
| Tier | Category | Methods | Notes |
|---|---|---|---|
| Tier 1 | Criterion & Reference Methods | MRI | Direct adipose tissue quantification, no assumptions |
| Tier 1 | Criterion & Reference Methods | 4-Compartment Models (4C) | Criterion gold standard for living subjects |
| Tier 1 | Criterion & Reference Methods | DEXA | 3-compartment model, high precision, clinical reference |
| Tier 2 | High-Quality Densitometry | Hydrostatic Weighing (UWW) | Classic 2-compartment density method |
| Tier 2 | High-Quality Densitometry | Bod Pod | Air displacement plethysmography, comparable to UWW |
| Tier 3 | Validated Field & Clinical Methods | Ultrasound (B-mode / A-mode) | Measures fat layer thickness; less operator-dependent than calipers |
| Tier 3 | Validated Field & Clinical Methods | Expert Skinfold Calipers | Highly dependent on technician skill; uses validated equations |
| Tier 3 | Validated Field & Clinical Methods | High-End Multi-Frequency Segmental BIA (e.g., InBody 970/770) | ≥6 frequencies, up to 1 MHz, 8-point electrodes |
| Tier 4 | Good Multi-Frequency BIA (Research/Clinical Grade) | Other MF-BIA devices (e.g., Seca mBCA, Tanita MC-780) | Reasonable accuracy; typical error ~3.5–5% vs DEXA (varies by population) |
| Tier 5 | Estimation & Basic Devices | US Navy Formula | Circumference-based; population averages; error typically >4–5% |
| Tier 5 | Estimation & Basic Devices | Single-Frequency BIA | Consumer devices; highly hydration-dependent; lowest electronic accuracy |
Visual guide
Visual estimates, even by professionals, are significantly less accurate than DEXA scans, no matter what some forum discussions might claim. That said, for contest or photoshoot preparation, visual assessments for conditioning are a practical method. In such cases, it's beneficial to seek guidance from a coach's trained eye for a more reliable evaluation.
Why are visual body fat comparisons so often misleading?
A few major factors explain why looking at photos rarely tells the whole story.
1. The same body fat percentage can look completely different, even at the exact same height
Body fat percentage only tells you the ratio of fat to your overall body weight. It does not reveal how much muscle you carry unless you factor in your scale weight to calculate your actual lean and fat mass.
Take two men who are both 180 cm (5 ft 11 in) tall and sit at 10% body fat:
- One weighs 70 kg (154 lb)
- The other weighs 90 kg (198 lb)
Even with identical body fat percentages, their physiques will not look similar at all.
The 90 kg individual has significantly more lean mass, along with more absolute fat mass.
- The 90 kg person has 9 kg of fat and 81 kg of lean mass.
- The 70 kg person has 7 kg of fat and 63 kg of lean mass.
This means the heavier man has 2 kg more fat, but a massive 18 kg more lean mass. That extra muscle creates a larger, rounder, and much fuller shape. Because of this, the heavier man will usually look leaner and more defined, despite both individuals sitting at exactly 10% body fat.
With 18 kg of extra muscle, his biceps, quads, and lats have a much larger circumference. This gives him a naturally wider and more developed silhouette.
2. The "peaks and valleys" effect of body topography
Most people can guess body fat fairly well if the subject has decent muscle mass. However, those guesses get highly inaccurate when looking at someone with average or below-average muscle.
It sounds counterintuitive, but visual leanness depends heavily on your body's physical contours, not just how thick your fat layer is. The 90 kg lifter has prominent muscle peaks. When a bicep flexes and peaks, it stretches the skin and subcutaneous fat thin over the top. At the same time, the valleys between muscles (such as the gap separating the bicep and tricep) run deeper because the muscles on either side bulge outward. This casting of deep shadows and sharp transitions creates a highly defined look.
The 70 kg man has smaller muscle bellies. While he carries 2 kg less total fat, that fat is spread over a smaller frame. The skin does not stretch as tightly over his muscles, which leaves him with softer transitions and less defined separation.
This dynamic only holds true if both people are roughly the same height. It explains why a simple body fat percentage can never fully describe how someone actually looks.
Fitness influencers frequently exploit this topographic effect to look much larger on screen than they are in person.
You might wonder how someone of your exact height and weight looks so much bigger. The secret is usually a lower body fat percentage. A leaner build creates deeper shadows and sharper muscle separation, making muscles pop on camera.
If you saw that same influencer standing next to an average person, you would instantly see their true size. Often, they are not actually massive; they are just incredibly lean, and the lens exaggerates their shape.
This also explains why heavy strongmen or powerlifters can look surprisingly lean, sometimes even showing visible abs, at higher body fat percentages. Their massive amount of lean muscle mass carries the weight differently.
This does not mean tracking body fat is useless. If you know someone's height, weight, and body fat percentage, you can get a very solid mental picture of their build.
3. Fat distribution is highly individual
When we try to guess body fat, we usually focus on obvious areas like the shoulders, arms, chest, waist, and abs. We look at the core and the limbs because those are the areas on display.
But fat does not accumulate evenly. One person might store fat primarily in their thighs, hips, glutes, or lower back, while another stores it mostly around their stomach.
A DEXA scan measures fat distribution across your entire body to find your true overall percentage. Visual guesses, on the other hand, rely on just a few visible areas. Since everyone stores fat differently, two people with identical body fat levels can look entirely different.
Coaches frequently rely on calipers or DEXA scans to track progress, but when bodybuilders step on stage, they are judged strictly on visual conditioning. Precise body fat percentages simply do not enter the equation. Many trainers love to say the eyes are the ultimate judge, but human vision still cannot match the precision of an MRI or a DEXA scan.
Long before these high-tech tools became common, lifters used a much simpler rule of thumb: bulk until your abs fade, then cut until they show up again. You do not need cutting-edge technology to get results.
If you cannot get a DEXA scan, the free MacroCodex app has a built-in US Navy body fat calculator. The classic formula it uses is more than enough to establish a solid baseline.
| Category | Male Body Fat % | Female Body Fat % |
|---|---|---|
| Essential Fat | 2–5% | 10–13% |
| Athletic | 6–13% | 14–20% |
| Fitness | 14–17% | 21–24% |
| Average | 18–24% | 25–31% |
| Obese | 25%+ | 32%+ |
Table source: American Council on Exercise (ACE). ACE Personal Trainer Manual (multiple editions), based on body fat classification ranges derived from: Heyward, V. H. Advanced Fitness Assessment and Exercise Prescription. Human Kinetics.
To translate male body fat targets to female equivalents, you can generally just add 9 to 10 percentage points.
Here is how that looks in practice:
- If the recommendation for a man is to cut to 10-12%, the target for a woman is about 19-21%.
- If a man is advised to bulk up to 17%, the equivalent target for a woman is roughly 26-27%.
This quick adjustment makes it easy to convert standard fitness guidelines between genders.
workout-not-build
Workout does not build muscle.
Workout triggers a process which builds muscle using supplies from diet.
A person working out consistently triggers this BUILD process, but if the diet is not on point, this process halts prematurely and doesn't build anything.
The supplies are fats, carbs, and proteins, which all add up to total calories.
These are needed in the right proportion for growth; too low fat = hormones not working optimally, not enough joint lubrication, too low carbs = not enough performance, glycogen stores to fuel the workout, too low proteins = not enough building blocks for muscle, too low calories (coupled with low bodyfat% which is body's energy reserve) = not enough energy to sustain muscle protein synthesis.
muscle loss
A lot of people stress out about losing muscle when they go on a cut, but most of that worry is misplaced. Unless you're using lab grade tools to track your actual tissue, why assume the muscle is gone just because you're getting smaller? In healthy adults, skeletal muscle accounts for roughly 40 to 50% of fat free mass (FFM). Men are generally on the higher side of that range. Women tend to be lower because a bigger chunk of their lean mass is made of organs and essential fat. Lean Body Mass (LBM) covers everything that isn't fat, including bones, skin, organs, and especially water. Glycogen and water storage can swing your FFM and LBM numbers wildly. If an average guy cuts out carbs for just two or three days, he can lose about 2 to 3 kg (4 to 6 lb) of water weight. If he steps on a body composition scanner, it will likely show a drop in fat free mass or a lower FFMI. In reality, he hasn't lost any muscle tissue at all. Actual loss of muscle tissue is actually quite rare. You can't gauge it by feeling small or looking flat. Dehydrating yourself might make your muscles look more defined, but it doesn't mean you've gained anything. Likewise, losing glycogen might make you shrink a bit, but that isn't the same as actually losing tissue. Significant muscle loss usually happens in very specific scenarios: muscle wasting diseases, extreme crash diets, or being completely bedridden. If you're eating enough protein and staying active, your risk is low. Since skeletal muscle is about 70% water, what most people mistake for muscle loss is usually just a change in how full the muscles look. Our protocol suggests lifting heavy once or twice a week. That provides more than enough intensity to keep your gains. Research suggests that you only need about one third of your original training volume to maintain muscle. If you do lose a tiny bit of ground, you will gain it back fast during your next bulk, or even during a recomposition if you're a beginner. Keep in mind that even a DEXA scan doesn't measure muscle tissue directly. It measures lean body mass. If your DEXA numbers go down, it doesn't automatically mean your muscles are actually smaller.
#body-composition
Track Your Weight Trend, Not Your Daily Weight
Stepping on the scale every morning can be incredibly frustrating, mostly because our weight naturally bounces around. It's completely normal for your weight to shift over the course of a single day or week simply because of water retention, recent meals, and glycogen levels. Instead of stressing over those daily ups and downs, it's much more helpful to look at the overall trend over several weeks.
Why bodyfat% matters?
Staring at the scale and obsessing over a single number is an easy trap to fall into, but that weight doesn't tell the whole story. Your body is far more than just a single lump of mass. Instead, it is split into two main parts: fat mass and lean mass. Fat mass is pretty self-explanatory, while lean mass is everything else, including your muscles, bones, organs, and water weight.
Tracking both your total weight and your body fat percentage reveals the actual ratio between these two components. This gives you a much clearer understanding of your true baseline and lets you accurately measure the quality of your progress over time.
Take a look at the image below. Both men stand at 180 cm (5'11") and weigh 80 kg (176 lbs). Despite sharing identical stats, one looks soft and out of shape, while the other looks lean and athletic. The deciding factor here is their body fat percentage.
Man 1 carries a higher body fat percentage of 30%. This means 30% of his total weight comes from fat, leaving the remaining 70% as lean mass.
Man 2 sits at a much lower body fat percentage of 10%. Only 10% of his weight is fat, while a massive 90% is lean mass.
These numbers make their physical differences immediately obvious. For Man 1 to build a leaner, more athletic build, he needs to focus on dropping fat while packing on lean mass.
True body transformation isn't just about moving the scale up or down. It's about shifting your overall body composition to find the right balance between fat and lean tissue.
Look at it this way. If someone called you and only shared their height and weight, you would have almost no idea what they actually looked like in person. But if they added their body fat percentage to the mix, you'd immediately have a highly accurate mental picture of their build.
