Chin Ups vs Cable Lat Pulldown
FR : Tractions supination ↔ Tirage vertical pronation
Swapping Chin Ups (Bodyweight) for Cable Lat Pulldown (Cable) retains 100% overlap; expect pulley-guided continuous line of pull. Compare exact 17-muscle fractional recruitment before swapping equipment mid-session.
Weighted Muscle Overlap

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 Chin Ups for Cable Lat Pulldown.
| Muscle Group | Chin Ups | Cable Lat Pulldown | Leverage Shift |
|---|---|---|---|
| Lats (Latissimus Dorsi) | Primary (45%) | Primary (45%) | Matched |
| Upper Back (Rhomboids / Mid-Traps) | Secondary (25%) | Secondary (25%) | Matched |
| Biceps Brachii & Brachialis | Secondary (20%) | Secondary (20%) | Matched |
| Forearms & Grip | Secondary (10%) | Secondary (10%) | Matched |
Load & Volume Conversion: Chin Ups → Cable Lat Pulldown
Worked weight heuristic: a 70 kg set on Chin Ups (Bodyweight) maps roughly to 45 kg on Cable Lat Pulldown (Cable; 2.5 kg jumps, curve: constant cable tension at peak lengthened position). Calibrate set 1 at RPE 8 so e1RM history for Chin Ups remains unskewed. Zero anatomical muscles are dropped between Chin Ups and Cable Lat Pulldown; 1:1 weekly set volume carries straight across.
