Load & Volume Conversion: Cable Low Fly Crossovers → Incline Dumbbell Fly

Worked weight heuristic: a 45 kg set on Cable Low Fly Crossovers (Cable) maps roughly to 38 kg per hand on Incline Dumbbell Fly (Dumbbell; 2 kg jumps, curve: extended end-range stretch with neutral wrist path). Calibrate set 1 at RPE 8 so e1RM history for Cable Low Fly Crossovers remains unskewed. Zero anatomical muscles are dropped between Cable Low Fly Crossovers and Incline Dumbbell Fly; 1:1 weekly set volume carries straight across.
