- Adjust if performance, adherence or recovery slip
Common mistakes
- ❌ Stacking too many methods at once
- ❌ Ignoring sleep, protein and technique
- ❌ Copying protocols without scaling
Takeaway
Lean bulk only matters if it helps you decide what to do this week, at what dose, and how to measure it.
