Crab Walk vs Cable Crunch
FR : Crab Walk ↔ Cable Crunch
Swapping Crab Walk (Bodyweight) for Cable Crunch (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
100%
Sum of min(coef A, coef B)
Primary Equipment
Bodyweight → Cable
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 Crab Walk for Cable Crunch.
| Muscle Group | Crab Walk | Cable Crunch | Leverage Shift |
|---|---|---|---|
| Abdominals & Trunk Bracing | Primary (100%) | Primary (100%) | Matched |
Load & Volume Conversion: Crab Walk → Cable Crunch
Worked weight heuristic: a 70 kg set on Crab Walk (Bodyweight) maps roughly to 45 kg on Cable Crunch (Cable; 2.5 kg jumps, curve: constant cable tension at peak lengthened position). Calibrate set 1 at RPE 8 so e1RM history for Crab Walk remains unskewed. Zero anatomical muscles are dropped between Crab Walk and Cable Crunch; 1:1 weekly set volume carries straight across.
