What is a realistic monthly gain for recomp?
0.4–1.2% of bodyweight, depending on training experience. The calculator returns your band.
Muscle Gain Calculator body recomposition
body recomposition only works at a calorie position the body can convert into muscle, not fat. This page sets a daily surplus, protein anchor and monthly gain target for recomp that the research supports — small enough to stay lean, large enough that training adapts.
The right pace for body recomposition
Lean gain runs at 0.4–1.2% of bodyweight per month depending on training history. The calculator scales the surplus to match — 250–400 kcal/day, no more — because anything above that band lands as fat regardless of training quality.
Aggressive bulks feel productive in week 2. By week 8 they require a long cut that erases the lean gains alongside the fat.
Protein, training and recovery for body recomposition
Protein at 1.8 g/kg, training that progressively overloads the main lifts, sleep that supports recovery — those three together make the surplus into muscle. Without all three, extra calories are just storage.
Track strength on key lifts week to week. If they move, the plan works; if they plateau for 3+ weeks at the same bodyweight, technique or recovery is the bottleneck — not calories.
How AJYX manages body recomposition
Inside AJYX, calories adjust as the weight trend responds. recomp stay inside the lean-gain band without recalculating manually — the app trims when gain runs hot and nudges up when it stalls.

FAQ
Should recomp eat more than the calculator says?
Only if monthly gain falls below the lower end of the band for 3+ weeks. Otherwise extra calories are fat, not muscle.
How long should body recomposition last?
8–16 weeks of focused gain followed by a short maintenance or mini-cut. Continuous bulks past 16 weeks see fat outpace muscle as the ratio worsens.
