Cable Fly Crossovers vs Around The World
Swapping Cable Fly Crossovers (Cable) for Around The World (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 Fly Crossovers for Around The World.
| Muscle Group | Cable Fly Crossovers | Around The World | Leverage Shift |
|---|---|---|---|
| Chest (Pectoralis Major) | Primary (85%) | Primary (85%) | Matched |
| Shoulders (Deltoids) | Secondary (15%) | Secondary (15%) | Matched |
Load & Volume Conversion: Cable Fly Crossovers → Around The World
Worked weight heuristic: a 45 kg set on Cable Fly Crossovers (Cable) maps roughly to 38 kg per hand on Around The World (Dumbbell; 2 kg jumps, curve: extended end-range stretch with neutral wrist path). Calibrate set 1 at RPE 8 so e1RM history for Cable Fly Crossovers remains unskewed. Zero anatomical muscles are dropped between Cable Fly Crossovers and Around The World; 1:1 weekly set volume carries straight across.
