Cable Biceps Curl vs Dumbbell Drag Curl

FR : Cable Biceps Curl ↔ Drag Curl

Swapping Cable Biceps Curl (Cable) for Dumbbell Drag 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 Drag Curl.

Muscle Group Cable Biceps Curl Dumbbell Drag 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 Drag Curl

Worked weight heuristic: a 45 kg set on Cable Biceps Curl (Cable) maps roughly to 38 kg per hand on Dumbbell Drag 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 Drag Curl; 1:1 weekly set volume carries straight across.
