Energy Balance & Calorie Surplus Planner

Calculate the exact weekly calorie surplus required for lean muscle gains based on your training experience level.

Maximizing Muscle Hypertrophy vs. Fat Gain

To build new muscle, your body requires an anabolic **Calorie Surplus**. However, the rate of muscle synthesis is genetically limited by your training experience. Beginners can build muscle rapidly and require a larger surplus (~15%), whereas advanced lifters building tiny fractions of muscle require a small surplus (~5%) to prevent fat gain.

Gereelde Vrae

Your body cannot synthesize muscle faster than its biological rate. Excessive calories will simply be stored as adipose tissue (fat).

Beginners or individuals with high body fat can build muscle in a deficit (recomposition), but lean advanced lifters require a surplus.
