Dumbbell Skullcrusher — Muscles Worked & RPE Load Guide
Dumbbell Skullcrusher targets Triceps Brachii as primary movers (1.0× set credit). Extended end-range stretch with neutral wrist path.
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 |
|---|---|---|---|---|
| Triceps Brachii | Primary (1.0× set) | 100% | 6–14 sets/wk (MRV 18) | 2–4x / week · Evidence |
