Reverse crunches — Muscles Worked & RPE Load Guide
Reverse crunches targets Abdominals & Trunk Bracing as primary movers (1.0× set credit). Leverage-dependent resistance arc across joint flexion.
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 |
|---|---|---|---|---|
| Abdominals & Trunk Bracing | Primary (1.0× set) | 100% | 6–20 sets/wk (MRV 25) | 3–6x / week · Evidence |
Reverse crunches Worked Wathan RPE Prescription Table (kg)
Worked kg values computed for Reverse crunches using a worked 50.0 kg reference 1RM (Barbell) rounded to 2.5 kg bodyweight / free increments. Mechanics: Relative bodyweight kinematics & core bracing; resistance curve: Leverage-dependent resistance arc across joint flexion.
