Dumbbell Decline Bench Press — Muscles Worked & RPE Load Guide
Dumbbell Decline Bench Press targets Chest as primary movers (1.0× set credit) alongside Triceps Brachii, Shoulders (0.5× synergist 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 |
|---|---|---|---|---|
| Chest (Pectoralis Major) | Primary (1.0× set) | 55% | 10–20 sets/wk (MRV 22) | 2–4x / week · Evidence |
| Triceps Brachii | Secondary (0.5× set) | 30% | 6–14 sets/wk (MRV 18) | 2–4x / week · Evidence |
| Shoulders (Deltoids) | Secondary (0.5× set) | 15% | 8–22 sets/wk (MRV 26) | 2–6x / week · Evidence |
