Eat to grow, not to bloat. A measured surplus, the right rate of gain, and how to know exactly when it is time to switch back to a cut.
A lean bulk is a cut run in reverse: a small, boring number held for a long time.
10–15% above maintenance is the whole thing. That is usually 200–350 calories. Larger surpluses do not build muscle faster; they build the fat you will spend the next cut removing.
If the scale is moving faster than that, you are not bulking harder — you are just gaining fat.
Switch back when the mirror says so, not the calendar. For most people that is somewhere around the point where the abs blur. Cut, reveal, repeat.
Losing fat without losing muscle is a numbers game. Here is the exact deficit, the protein floor, and the refeed cadence we program for a cut that actually holds.
The one-gram-per-pound rule gets you close, but context changes everything. What the research says for cutting, maintaining, and building.
Two of the most popular splits, head to head. Frequency, volume and recovery — and how to pick the one your schedule can actually sustain.
