Bench Press vs Dumbbell Bench Press
FR : Développé Couché ↔ Développé couché haltères
Swapping Bench Press (Barbell) for Dumbbell Bench Press (Dumbbell) retains 100% overlap; expect independent unilateral stabilization. Compare exact 17-muscle fractional recruitment before swapping equipment mid-session.
Weighted Muscle Overlap
100%
Sum of min(coef A, coef B)
Primary Equipment
Barbell → Dumbbell
Same rep/load measurement family
Load Transfer Protocol
Target RPE 7.5–8.5
Never assume 1:1 kg across leverages
Side-by-Side 17-Muscle Recruitment Delta
How primary mover (1.0× set) and synergist (0.5× set) allocation changes when swapping Bench Press for Dumbbell Bench Press.
| Muscle Group | Bench Press | Dumbbell Bench Press | Leverage Shift |
|---|---|---|---|
| Chest (Pectoralis Major) | Primary (50%) | Primary (50%) | Matched |
| Triceps Brachii | Secondary (30%) | Secondary (30%) | Matched |
| Shoulders (Deltoids) | Secondary (20%) | Secondary (20%) | Matched |
Load & Volume Conversion: Bench Press → Dumbbell Bench Press
Worked weight heuristic: a 100 kg set on Bench Press (Barbell) maps roughly to 38 kg per hand on Dumbbell Bench Press (Dumbbell; 2 kg jumps, curve: extended end-range stretch with neutral wrist path). Calibrate set 1 at RPE 8 so e1RM history for Bench Press remains unskewed. Zero anatomical muscles are dropped between Bench Press and Dumbbell Bench Press; 1:1 weekly set volume carries straight across.
