Cut, Bulk or Recomp?
The most asked question in any fitness community, and it has an answer. Two numbers decide it, and neither of them is how you feel about the mirror today.
Last updated: 30 September 2026
Overview
The most asked question in any fitness community, under a dozen titles: deficit or maintenance, keep bulking or cut, am I lean enough to go back up, should I cut 5kg first.
It has an answer, and it comes from two numbers rather than from how the mirror looked this morning.
Quick Answer
Beginners and people returning after a break should usually eat around maintenance and train, because they gain muscle and lose fat at once. Everyone else should cut if body fat is high, and gain if it is low. Roughly 15 to 20 percent for men and 25 to 30 percent for women are the usual points to cut first.
Key Points
- Training age decides whether recomp is available to you.
- Body fat decides the direction for everyone else.
- Higher body fat, cut first. Lower, gain.
- Pick one and give it three months.
- Switching every fortnight is the actual mistake.
The decision
Step one: are you new, or returning?
If you have trained seriously for less than a year, or are coming back after months off, recomposition is genuinely available: eat around maintenance, train hard, get your protein up, and gain muscle while losing fat. Nobody else gets this and it does not last, so use it.
Step two: everyone else, look at body fat.
| Body fat | Men | Women | Do |
|---|---|---|---|
| High | Above 20% | Above 30% | Cut |
| Moderate | 15 to 20% | 25 to 30% | Either. Cut if unsure |
| Lower | 10 to 15% | 20 to 25% | Gain |
| Low | Under 10% | Under 20% | Gain |
Estimating it is covered in how to estimate body fat, and the honest answer is that everybody is bad at it. Most people guess themselves five to eight points leaner than they are.
Why higher body fat means cut first
Three reasons that are all about the next phase, not this one.
A surplus at higher body fat puts on proportionally more fat, so you end a bulk further from where you want to be. Insulin sensitivity is better at lower body fat, which modestly favours the muscle gain you are paying for. And the diet at the end of a bulk that started high is a long, miserable one.
Why lower body fat means gain
Building muscle in a deficit is slow at best and impossible for most trained lifters. Below roughly 10 percent for men, hormonal function, sleep, mood and training performance all degrade — see not eating enough.
If you are lean and unhappy with how you look, the problem is almost never remaining fat. It is missing muscle, and the answer is to eat.
How long to run it
| Phase | Length | End it when |
|---|---|---|
| Cut | 8 to 16 weeks | You hit the target, or performance and mood suffer |
| Gain | 3 to 6 months | Body fat reaches a level you dislike training at |
| Recomp | 6 months plus | You stop being a beginner |
| Maintenance | As long as you like | Whenever you want to change something |
The most common mistake in the whole subject is running each phase for three weeks. Nothing visible happens in three weeks, so you conclude it is not working and switch, and a year of alternating produces exactly nothing.
The honest answer to "but I want both"
Everybody wants both. Outside the beginner and returning cases, you largely have to pick, and the reason is arithmetic rather than discipline: muscle needs energy left over and fat loss needs energy missing.
Maintenance is a real and underrated third option. Eating at maintenance and training hard keeps you where you are, keeps the lifts moving, and is a perfectly reasonable place to spend six months while life is busy. Nothing requires you to be in a phase.
Common Mistakes
| Mistake | Why it causes problems | Better approach |
|---|---|---|
| Switching every 3 weeks | Nothing happens in 3 weeks | Give it 3 months |
| Bulking at 25% body fat | Mostly buys fat, and a long diet after | Cut first |
| Cutting at 10% body fat | Costs muscle, mood and performance | Eat |
| Recomping after 5 years trained | It stopped being available | Pick a direction |
| Guessing body fat from the mirror | Almost everyone guesses too lean | Estimate properly |
| Deciding from today's mirror | Lighting, water, food, time of day | Decide from the numbers |
Frequently Asked Questions
Should I cut or bulk?
If you are new or returning, neither: eat at maintenance and train. Otherwise cut above roughly 20 percent body fat for men or 30 percent for women, and gain below that.
Can I build muscle and lose fat at the same time?
Beginners and returning lifters reliably can. Experienced lifters can only barely, and only in specific circumstances.
How lean should I be before bulking?
Around 15 percent for men and 25 percent for women is a comfortable starting point. Higher than that and you spend the bulk gaining fat you will have to diet off.
How long should a cut be?
Eight to sixteen weeks, then a break at maintenance. Longer than about four months and adherence, mood and performance all start costing you more than the fat loss is worth.
