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 |
|---|---|---|---|---|
| Shoulders (Deltoids) | Primary (1.0× set) | 45% | 8–22 sets/wk (MRV 26) | 2–6x / week · Evidence |
| Upper Back (Rhomboids / Mid-Traps) | Primary (1.0× set) | 40% | 10–20 sets/wk (MRV 24) | 2–4x / week · Evidence |
| Traps (Upper & Mid Trapezius) | Secondary (0.5× set) | 15% | 6–18 sets/wk (MRV 26) | 2–4x / week · Evidence |
