Plans for Your Body · Weight & body composition
The lean physique plan
Build the muscle. Then take the fat off it.
The goal: A lean physique is enough muscle with little enough fat on top. Lift 3–4 times a week with 10–20 hard sets per muscle, add load or reps every week, eat about 1.6–2.2 g of protein per kg, then cut at 0.5–1% of body weight a week while keeping the training heavy. Measure strength, waist and photos, not just weight.
Most people try to get lean by dieting. They get smaller, not leaner, because there was never much muscle under the fat. A lean physique is built first and revealed second. This plan gives you the training, the protein and the order of operations, with numbers taken from the research rather than a magazine.
- BuildLift 3–4×/week · 10–20 hard sets per muscle · add weight or reps weekly
- Feed1.6–2.2 g/kg protein · real food · small surplus or maintenance
- RevealCut 0.5–1% a week · keep the weights heavy · then maintain
Dieting makes you smaller. Training decides what’s left.

02 Why it matters
Lean is a ratio, not a weight.
The default
Lots of cardio, a strict diet, light weights for ‘tone’. You lose fat and muscle in roughly equal measure, end up the same shape only smaller, and regain it as fat.
The better bet
Muscle is built by progressive, hard resistance training and fed by protein. Train for growth, then lose fat slowly enough that the training keeps the muscle. Beginners and people returning to training can often do both at once.
Why it matters beyond looks
Muscle is where most of the glucose from a meal goes. More muscle and less fat means better insulin sensitivity, blood sugar and blood pressure. The mirror is a side effect.
Knowing what builds muscle saves you years of doing what doesn’t. Here’s the mechanism.
03 How it works
Tension builds it. Protein feeds it. Progress keeps it coming.
Muscle grows when it’s made to work hard against resistance, repeatedly, over weeks, and the body has the protein to rebuild it bigger. Fat comes off when you eat a little less than you burn. The trick is running both without one wrecking the other.
- Mechanical tension
- The main growth signal. Sets taken close to failure produce it, whether the weight is heavy (5 reps) or moderate (20+ reps). In Schoenfeld’s meta-analysis, light and heavy loads built similar muscle; heavy loads built more strength.
- Volume
- Hard sets per muscle per week. More sets build more muscle, up to a point; about 10 or more a week per muscle is a sound target for most people.
- Frequency
- With weekly volume equal, training a muscle once or three times a week builds about the same. Twice a week is the practical way to fit the volume in without junk sets.
- Progressive overload
- Add weight or reps over time. If the log isn’t moving, the muscle isn’t either.
- Protein
- In a McMaster meta-analysis of 49 trials, protein boosted lifting gains up to about 1.6 g/kg a day, with the upper confidence limit near 2.2 g/kg. During a cut, needs go up.
- Energy balance
- A small surplus helps trained people build fastest. A deficit takes fat off. Beginners, returning lifters and people with more fat can ‘recomp’, building muscle while losing fat, at maintenance or a small deficit.
04 The program
Measure. Build. Cut. Then hold it.
Measure · Week 0
Get numbers you can beat.
- Waist and photossame light, same pose, monthly
Waist at the belly button; front, side and back photos. These show recomposition when the scale doesn’t.
- Strength logevery session
Exercise, weight, reps, and how many reps you had left. This is the most important document in the plan.
- Body weight7-day average
Weigh daily, look at the weekly average. You’ll need it to steer the surplus and the cut.
- Body compositionoptional, DEXA
Measures fat and lean mass separately. Once at the start, once after each phase.
Build · Months 1–6 (longer if you’re new)
Train for growth. Eat to support it.
If you’re new to lifting or carrying a fair amount of fat, eat at maintenance or a slight deficit and recomp. If you’re already lean and trained, eat in a small surplus: aim to gain about 0.25–0.5% of body weight a month, no faster.
- Split3–4 days a week
Three full-body sessions, or four sessions split upper/lower. Either hits each muscle twice a week.
- Exercises5–7 per session
Per session: a squat or leg press, a hinge (Romanian deadlift, hip thrust), a horizontal push and pull, a vertical push and pull, plus one or two for arms, calves or delts. Machines and dumbbells are fine.
- Sets and reps10–20 hard sets per muscle per week
Main lifts: 3–4 sets of 5–10 reps. Accessories: 2–3 sets of 10–20 reps. Stop 0–3 reps short of failure; the last reps should be slow and hard.
- Progressiondouble progression
Pick a rep range, e.g. 8–12. When you hit the top of the range on every set with good form, add the smallest weight jump (2.5–5%) and start again at the bottom.
- Deloadevery 6–8 weeks
One easier week: half the sets, same weights. Then build again.
- Protein1.6–2.2 g/kg, across 3–4 meals
Around 0.4 g/kg per meal, from meat, fish, eggs, dairy or legumes. Build every meal on a solid protein dose. With kidney disease, ask your doctor first.
- Real foodprotein first
Build meals on protein, vegetables and natural fats: fish, meat, eggs, dairy, legumes, nuts. Protein and fibre keep you full and flatten glucose spikes. Carbs around training help performance; the rest of the plate is protein and vegetables.
- Cardio2–3×/week, plus daily walking
Good for your heart and recovery. Keep hard sessions away from leg days so they don’t eat into your lifting.
- Sleep7+ hours
One short night measurably worsens insulin sensitivity, blood sugar and appetite the next day. The cheapest part of the protocol, and the most skipped. Short sleep shifts weight loss from fat to muscle and blunts recovery. It’s training, too.
Cut · 8–16 weeks
Take the fat off. Keep the weights heavy.
- Rate of loss0.5–1% of body weight a week
The pace recommended for natural athletes to keep muscle. The leaner you get, the closer to 0.5% you should be.
- Protein upabout 2.3–3.1 g per kg of lean mass
The evidence-based range for lean lifters in a deficit. Roughly 2–2.4 g/kg of body weight for most people. It also helps with hunger.
- Trainingsame loads, slightly fewer sets
Keep the heavy work. You may cut accessory sets by a third if recovery suffers. Strength holding steady usually means muscle is staying.
- Sugar and refined carbscut hard
Sugar, sweet drinks, juice, white flour and most packaged snacks. The fastest lever on insulin, blood sugar and triglycerides. Refined carbs are easy calories that don’t fill you. Keep carbs from whole foods, around training.
- Eating windowoptional
Eat inside a fixed window and not outside it. Fewer insulin spikes per day, fewer chances to overeat. Fit 3–4 protein-heavy meals into it. Don’t compress so hard that you can’t hit your protein.
- Alcoholminimal
Empty calories that hurt sleep and recovery. Keep it rare while cutting.
When to stop the cut
Stop if strength drops week after week, sleep falls apart, you lose your period, or food becomes all you think about. Return to maintenance for a few weeks. Very low body fat isn’t a health goal.
Supplements · optional, with your doctor’s OK
One with strong evidence. One for convenience.
- Creatine monohydrate3–5 g a day, any time
Taken with resistance training, it added about 1.4 kg more lean mass and more strength than training alone in adults over 50, in pooled trials. Small trials hint at better memory; that evidence is thinner. It raises blood creatinine, which can make a kidney test look worse than it is, so tell your doctor you take it. Skip it if you have kidney disease, or are pregnant or breastfeeding. The best-studied supplement for adding muscle and strength alongside training. Expect 1–2 kg of water on the scale at first.
Find it on Amazon: Creatine monohydrate - Whey protein20–40 g a day, only if food falls short
A convenient way to reach your protein target, nothing more. With resistance training, extra protein added a modest 0.3 kg of lean mass in pooled trials, with no further gain once total intake passed about 1.6 g per kg of body weight. If you already eat enough protein, skip it. Avoid with a milk allergy; with kidney disease, ask before raising protein. Makes the daily protein target easy. Beyond about 1.6 g/kg it adds nothing.
Find it on Amazon: Whey protein
Maintain · after the cut
Hold it, then decide what’s next.
- Back to maintenanceover 2–3 weeks
Add food until the weekly average levels off. Keep protein and training exactly as they were.
- Repeat or holdyour call
Another build-and-cut cycle adds more muscle. Or hold where you are: training 2–3 times a week keeps most of it.
05 The rules
Short list. No exceptions.
Choose
- Compound lifts, done with full range of motion
- A training log, every session
- Protein at every meal
- 7–9 hours of sleep
Avoid
- Light weights for ‘toning’. There’s no such thing
- Program-hopping every few weeks
- Cutting fast, or cutting forever
- ‘Fat-burner’ supplements
Non-negotiables
- Add weight or reps over time, or you’re not progressing.
- Keep training heavy while you cut.
- Judge by strength, waist and photos, not the scale alone.
- Talk to a medical doctor before you start a supplement, and before a hard cut if you have a medical condition or an eating-disorder history.
06 Checkpoints
What to track, and what good looks like.
Muscle gain is slow and the scale is noisy. Track the things that move.
| What | Target | How and when |
|---|---|---|
| Strength | Up on most lifts every 2–4 weeks while building; holding while cutting | Your training log. The best single proxy for muscle you have. |
| Waist-to-height | <0.5; most lean people sit around 0.40–0.45 | Monthly, at the belly button, after breathing out. |
| Weekly average weight | Build: +0.25–0.5% a month · Cut: −0.5–1% a week | Daily weigh-ins, 7-day average. |
| Photos | Visible change every 2–3 months | Same light, same poses, same time of day. |
| Lean mass (DEXA) | Up after a build; held after a cut | Optional, at the end of each phase. |
Realistic muscle gain for a natural lifter slows a lot after the first year or two. Anyone promising you 10 kg of muscle in 12 weeks is selling something.
07 Where experts disagree
Where the experts don’t agree.
The basics are settled: lift hard, progress, eat protein. The arguments are at the margins.
How much volume is enough?
More is better, up to a point: Schoenfeld
Meta-analyses show a dose-response: more weekly sets build more muscle, and some trials found gains continuing beyond 20 sets a week.
Less, but harder: Steele, Fisher
Beyond a moderate number of hard sets, extra volume mostly adds fatigue. A few all-out sets per muscle get most of the result.
Our read Start around 10–12 hard sets per muscle per week. Add sets for lagging muscles if you recover well. Effort per set matters as much as count.
How much protein?
About 1.6 g/kg: Phillips, Morton
In pooled trials, extra protein stopped adding muscle around 1.6 g/kg a day. More isn’t harmful, just unnecessary for most.
Higher: Helms, Antonio
Lean lifters in a deficit likely need more: Helms’s review puts it at 2.3–3.1 g per kg of lean mass. Antonio’s trials fed trained lifters around 3.4 g/kg for weeks with no harmful changes in routine blood tests, and in one, a little more fat came off.
Our read 1.6 g/kg is the floor when building; aim higher, about 2–2.4 g/kg, when cutting. Antonio’s follow-up crossover trial found no body-composition edge from very high intakes, so going past that is a matter of appetite and preference, not extra muscle.
Bulk and cut, or recomp?
Bulk and cut: traditional bodybuilding
A surplus builds muscle fastest; a separate cut removes the fat. Cleaner signals, faster results for trained lifters.
Recomp: Barakat et al.
With progressive training and enough protein, many people, even some trained ones, can gain muscle while losing fat at maintenance or a small deficit.
Our read New, returning or carrying fat? Recomp. Already lean and trained? Small surplus, then a short cut.
08 Limits
What this plan can’t fix.
Your genetics
Frame, muscle insertions, where you store fat and how fast you grow vary a lot between people. Training and diet move everyone; they don’t make everyone look the same.
Very low body fat
Stage-lean isn’t a stable or healthy state. Hormones, mood, sleep and, in women, periods suffer. Lean and strong you can hold all year is the goal.
Injuries and medical limits
Joint problems, heart conditions and some medications need a doctor’s or physiotherapist’s input before heavy training. Get it; then train around it.
The plan builds what your body can build. It doesn’t choose your bones.

10 Questions
Questions, answered plainly.
Can I build muscle and lose fat at the same time?
Yes, if you’re new to lifting, returning after a break, or carrying a fair amount of fat. Lift progressively, eat 1.6–2.2 g/kg of protein, and eat at maintenance or a small deficit.
How many sets per week do I need to build muscle?
About 10–20 hard sets per muscle per week, taken within 0–3 reps of failure. Start at the low end and add sets if you’re recovering well and progress stalls.
Heavy weights or high reps?
Both build muscle if you take sets close to failure. Heavier loads (5–10 reps) build more strength. Most programs use both.
How much protein do I need to build muscle?
About 1.6 g per kg of body weight a day while building, more (around 2–2.4 g/kg) while cutting. Spread it over 3–4 meals. Higher intakes have looked safe in short trials in healthy lifters, but they haven’t clearly added more muscle.
How fast should I cut?
0.5–1% of body weight a week. The leaner you are, the slower you should go to keep muscle.
Is creatine safe?
In healthy people, decades of research say yes at 3–5 g a day. It adds water weight at first. Discuss it with your doctor first, especially with kidney disease.
