Build muscle on a lean bulk without getting fat
Trains 4×/week, 72kg at 178cm, "hard gainer" who under-eats without realising. Wants to add muscle while keeping abs, not blow up on a dirty bulk.
- 1
Find the surplus: The Lean Bulk Calculator sets ~2,700 kcal/day — a modest ~250–300 kcal surplus, not a dirty bulk.
- 2
Hit the protein: The Protein Calculator targets ~145g/day (≈2g/kg), spread across meals for muscle protein synthesis.
- 3
Structure the day: Follows the 7-Day Muscle Building Meal Plan so hitting the surplus + protein is consistent, not guesswork.
- 4
Progress + review: Aims for ~0.25kg/week; if the scale climbs too fast, tightens the surplus to keep the gain lean.
Projection: A lean bulk realistically adds muscle slowly — often ~0.25kg/week early on, tapering over months. Illustrative only; genetics, training age, and consistency drive the real rate.
