Why a Calorie Surplus Builds Muscle
To gain lean mass, you must consume more calories than you burn so your body has the energy to grow new muscle tissue.
Finding Your Ideal Surplus
A controlled surplus of 200–300 kcal/day supports muscle growth while keeping fat gain low.
Training and Recovery
Proper resistance training and recovery are crucial. MadMuscles designs a progressive program and macro plan to match your surplus.
Clean Bulking Tips
Prioritize protein: 1.6 – 2.2 g per kg of body weight.
