Should I bulk and cut, or try to do both at once?

The question of whether to alternate between bulking and cutting phases or try to simultaneously lose fat and gain muscle — known as body recomposition or recomping — is one of the most debated topics in fitness. The honest answer is that it depends on who you are and where you are starting from.

What bulk and cut actually means

A bulk is a period of eating in a calorie surplus — typically 250 to 500 calories above TDEE — with the goal of maximising muscle gain. The surplus provides energy for muscle building, and the expectation is that some fat will also be gained in the process. A cut follows, eating in a calorie deficit to reduce the fat gained during the bulk while preserving as much muscle as possible. This cycle, when executed well, is the most reliable way for experienced lifters to make meaningful changes in body composition over time.

What body recomposition actually means

Body recomposition involves eating at or close to maintenance calories — neither a meaningful surplus nor a deficit — while training hard and eating high protein. The goal is to slowly gain muscle while slowly losing fat, resulting in a leaner, more muscular physique at approximately the same body weight. Research has confirmed that simultaneous fat loss and muscle gain is genuinely possible. A 2020 paper by Barakat and colleagues reviewed the evidence and concluded that recomposition is achievable even in trained individuals, not just beginners.

Who should do each

Beginners and people returning to training after a long break are the best candidates for body recomposition. In the early stages of training, muscles are highly responsive and the hormonal environment supports simultaneous muscle gain and fat loss more readily than in experienced lifters. People with higher body fat percentages also tend to recomp well because stored fat provides energy for muscle building even at maintenance calories. Experienced, lean lifters generally get better results from dedicated bulk and cut phases because their bodies have adapted significantly and muscle growth requires a more pronounced surplus to proceed at a meaningful rate.

The case for a lean bulk

For most people who want to gain muscle without excessive fat gain, a lean bulk — a modest surplus of 200 to 300 calories per day — is the most practical approach. It is fast enough to support meaningful muscle gain, modest enough to minimise fat gain, and easier to sustain than aggressive bulking. The 10 to 20 percent body fat range is a useful guide: bulk until approaching 20 percent, then cut back toward 10 to 12 percent, then repeat. This keeps the conditions favourable for muscle gain without accumulating excessive fat.

The bottom line

If you are new to training or carrying more body fat, a recomposition approach at maintenance calories with high protein and progressive training is a sensible starting point. If you are experienced, lean, and serious about muscle gain, a modest lean bulk followed by a cut will produce better results over the long term. There is no wrong answer — the best approach is the one you will maintain consistently.
