17-Muscle Fractional Recruitment & Weekly MEV–MRV Landmarks

Each working set ≥ RPE 6 triggers fractional hard-set credit toward Renaissance Periodization / Schoenfeld weekly hypertrophy landmarks.

Muscle Group Mechanical Role Effort Share Weekly Optimal Band (MEV–MAV) Frequency & Research
Chest (Pectoralis Major) Primary (1.0× set) 85% 10–20 sets/wk (MRV 22) 2–4x / week · Evidence
Shoulders (Deltoids) Secondary (0.5× set) 15% 8–22 sets/wk (MRV 26) 2–6x / week · Evidence
