Barbell Upright Row vs Cable Upright Row

FR : Barbell Upright Row ↔ Cable Upright Row

Swapping Barbell Upright Row (Barbell) for Cable Upright Row (Cable) retains 100% overlap; expect pulley-guided continuous line of pull. 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 Barbell Upright Row for Cable Upright Row.

Muscle Group Barbell Upright Row Cable Upright Row Leverage Shift
Shoulders (Deltoids) Primary (50%) Primary (50%) Matched
Traps (Upper & Mid Trapezius) Primary (30%) Primary (30%) Matched
Biceps Brachii & Brachialis Secondary (20%) Secondary (20%) Matched

Load & Volume Conversion: Barbell Upright Row → Cable Upright Row

Worked weight heuristic: a 100 kg set on Barbell Upright Row (Barbell) maps roughly to 45 kg on Cable Upright Row (Cable; 2.5 kg jumps, curve: constant cable tension at peak lengthened position). Calibrate set 1 at RPE 8 so e1RM history for Barbell Upright Row remains unskewed. Zero anatomical muscles are dropped between Barbell Upright Row and Cable Upright Row; 1:1 weekly set volume carries straight across.
