Muscle gain & bulking
How many calories do you need to build muscle?
Muscle needs resistance training and adequate protein; calories fuel the process. Without progressive overload, extra food mostly becomes stored energy—not contractile tissue.
Start at maintenance, then add
Estimate TDEE honestly, then add a controlled surplus—often discussed around a few hundred kcal/day for lean gains.
Use male preset or homepage calculator for examples.
BMR and TDEE: fueling training days
High-volume programs raise recovery needs; undereating stalls strength even if scale weight looks “fine.”
Calorie surplus for muscle: not a license to binge
See surplus guide for pacing.
Recovery tips
Sleep 7–9 hours when possible; distribute protein across meals; deload when joints or mood signal overload.
Surplus snapshots
Illustrative.
| Food / context | Typical serving | Approx. kcal |
|---|---|---|
| TDEE | 2,700 | example |
| Lean surplus | +300 | ~3,000 |
