Bulk or cut: where to start depending on your starting point (myth-free)

Published on 22 July 2026

The eternal gym question has a technical answer: it depends on your current body fat and training experience. Clear criteria to decide, and how to execute each phase.

Should I bulk or cut? is probably the most repeated question in the gym, and most of the answers going around are dogmas inherited from competitive bodybuilding. The technical answer depends on two variables: your current body fat percentage and your training experience.

The decision criteria

• If you are a beginner (less than 1-2 years of serious training): the answer is usually neither. In your first 12-18 months you can gain muscle and lose fat at the same time (recomposition) by eating around maintenance with high protein and training with progression. It is the only stage where this happens easily: take advantage of it.
• If your body fat is high (men above 18-20 per cent, women above 28-30 per cent): start by losing fat. It improves insulin sensitivity, the muscle-to-fat ratio of your future bulk and - not a minor point - psychological adherence.
• If you are lean (men below 12-14 per cent, women below 22-24 per cent) and have been training for a while: bulk. Gaining muscle requires a surplus; trying to grow in a deficit as an intermediate is rowing against the current.
• If you are in the middle zone: choose according to your aesthetic and psychological priority. Technically, both work.

How to bulk without overshooting

The classic dirty bulk mistake: gaining 8 kg in 3 months, 6 of which are fat. The evidence favours a moderate surplus:

• A surplus of 200-400 kcal/day above maintenance.
• Target rate: gaining 0.25-0.5 per cent of body weight per week (faster only if you are a beginner).
• Protein: 1.6-2.2 g/kg/day.
• Minimum useful duration: 4-6 months - muscle is built slowly; six-week mini-bulks give nothing time to happen.

How to cut without eating into your muscle

• A deficit of 300-500 kcal/day (15-20 per cent below maintenance).
• Rate: losing 0.5-1 per cent of body weight per week.
• High protein (2.0-2.7 g/kg in a deficit) and keep training heavy: strength training is the signal that tells the body which tissue to keep. Cutting on cardio and light weights is the recipe for losing muscle.
• When you reach your target, raise calories gradually back to maintenance; abrupt reverses regain fat quickly.

The mistake of treating it as identity

Bulking and cutting are temporary phases with a goal, not lifestyles. The sequence that is sustainable across years is: long, controlled bulking phases, then 6-10 week mini-cuts when body fat becomes uncomfortable, then back to building. And in both phases, the variable that determines the outcome most is the same: training with structured progression. You can generate a routine adapted to your current goal for free - the generator adjusts volume and intensity depending on whether you choose hypertrophy, fat loss or recomposition.

The third option: what the evidence says about recomposition

Framing it as "bulk or cut" assumes you have to choose. A 2020 review in the Strength and Conditioning Journal, by Barakat, Pearson, Escalante, Campbell and De Souza, tackled exactly the awkward question: can you build muscle and lose fat at the same time?

Their answer is yes, and not only in beginners or people carrying excess weight — where it was already established — but also in trained individuals. With fairly strict conditions, though. The authors point to two levers: progressive resistance training, and evidence-based nutritional strategies, with a high protein intake — above 2.0 g per kilo per day — as the common denominator across the studies where recomposition shows up.

One finding surprises even people with years in the gym: the review notes documented reductions in fat mass in well-trained subjects on hypercaloric intakes, specifically when the surplus came from increased protein.

The honest conclusion is that recomposition is not a shortcut. It is slower than a well-run bulk for gaining muscle, and slower than a well-run cut for losing fat. What it offers is not having to accept going backwards on either front, and for plenty of people who train for health and appearance — not to compete — that is worth more than optimising a single variable.
