A Lean Bulk Is a Precision Project
Bulks that add too fast add mostly fat. The right rate (0.25–0.5%/week) requires small surplus (200–400 kcal/day) and weekly trend review. Apps with trend-based adjustment keep the bulk lean; static apps drift into dirty territory.
How We Evaluated
- Trend-based surplus management
