Cable Biceps Curl vs Dumbbell Concentration Curl
Swapping Cable Biceps Curl (Cable) for Dumbbell Concentration Curl (Dumbbell) retains 100% overlap; expect independent unilateral stabilization. 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 Cable Biceps Curl for Dumbbell Concentration Curl.
| Muscle Group | Cable Biceps Curl | Dumbbell Concentration Curl | Leverage Shift |
|---|---|---|---|
| Biceps Brachii & Brachialis | Primary (80%) | Primary (80%) | Matched |
| Forearms & Grip | Secondary (20%) | Secondary (20%) | Matched |
Load & Volume Conversion: Cable Biceps Curl → Dumbbell Concentration Curl
Worked weight heuristic: a 45 kg set on Cable Biceps Curl (Cable) maps roughly to 38 kg per hand on Dumbbell Concentration Curl (Dumbbell; 2 kg jumps, curve: extended end-range stretch with neutral wrist path). Calibrate set 1 at RPE 8 so e1RM history for Cable Biceps Curl remains unskewed. Zero anatomical muscles are dropped between Cable Biceps Curl and Dumbbell Concentration Curl; 1:1 weekly set volume carries straight across.
