Reverse Dumbbell Curl vs EZ Bar Reverse Curl
FR : Curl inversés haltères ↔ EZ Barre Curl Inversé
Swapping Reverse Dumbbell Curl (Dumbbell) for EZ Bar Reverse Curl (Ez) retains 100% overlap; expect alternative path. Compare exact 17-muscle fractional recruitment before swapping equipment mid-session.
Weighted Muscle Overlap
100%
Sum of min(coef A, coef B)
Primary Equipment
Dumbbell → Ez
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 Reverse Dumbbell Curl for EZ Bar Reverse Curl.
| Muscle Group | Reverse Dumbbell Curl | EZ Bar Reverse Curl | Leverage Shift |
|---|---|---|---|
| Forearms & Grip | Primary (55%) | Primary (55%) | Matched |
| Biceps Brachii & Brachialis | Primary (45%) | Primary (45%) | Matched |
Load & Volume Conversion: Reverse Dumbbell Curl → EZ Bar Reverse Curl
Worked weight heuristic: a 38 kg per hand set on Reverse Dumbbell Curl (Dumbbell) maps roughly to 57.5 kg on EZ Bar Reverse Curl (Ez; 2.5 kg jumps, curve: alternative curve). Calibrate set 1 at RPE 8 so e1RM history for Reverse Dumbbell Curl remains unskewed. Zero anatomical muscles are dropped between Reverse Dumbbell Curl and EZ Bar Reverse Curl; 1:1 weekly set volume carries straight across.
