Dumbbell Hammer Curl vs Cable Hammer Curl
Swapping Dumbbell Hammer Curl (Dumbbell) for Cable Hammer Curl (Cable) retains 100% overlap; expect pulley-guided continuous line of pull. Compare exact 17-muscle fractional recruitment before swapping equipment mid-session.
Side-by-Side 17-Muscle Recruitment Delta
How primary mover (1.0× set) and synergist (0.5× set) allocation changes when swapping Dumbbell Hammer Curl for Cable Hammer Curl.
| Muscle Group | Dumbbell Hammer Curl | Cable Hammer Curl | Leverage Shift |
|---|---|---|---|
| Biceps Brachii & Brachialis | Primary (65%) | Primary (65%) | Matched |
| Forearms & Grip | Primary (35%) | Primary (35%) | Matched |
Load & Volume Conversion: Dumbbell Hammer Curl → Cable Hammer Curl
Worked weight heuristic: a 38 kg per hand set on Dumbbell Hammer Curl (Dumbbell) maps roughly to 45 kg on Cable Hammer Curl (Cable; 2.5 kg jumps, curve: constant cable tension at peak lengthened position). Calibrate set 1 at RPE 8 so e1RM history for Dumbbell Hammer Curl remains unskewed. Zero anatomical muscles are dropped between Dumbbell Hammer Curl and Cable Hammer Curl; 1:1 weekly set volume carries straight across.
