Best Macro Split for Muscle Gain

Lean bulking typically works best with a controlled calorie surplus (often around 5-12%), high protein consistency, and enough carbohydrates to support training volume.

Bigger surpluses do not necessarily accelerate muscle gain proportionally. They usually increase fat gain. Start conservative, then adjust with measured data.

Review bodyweight trend and gym performance every 2-3 weeks and adjust calories in small steps rather than large jumps.
