Machine Iso-Lateral High Row vs T Bar Row
Swapping Machine Iso-Lateral High Row (Machine) for T Bar Row (Barbell) retains 100% overlap; expect bilateral free-bar coordination. 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 Machine Iso-Lateral High Row for T Bar Row.
| Muscle Group | Machine Iso-Lateral High Row | T Bar Row | Leverage Shift |
|---|---|---|---|
| Upper Back (Rhomboids / Mid-Traps) | Primary (35%) | Primary (35%) | Matched |
| Lats (Latissimus Dorsi) | Primary (28%) | Primary (28%) | Matched |
| Biceps Brachii & Brachialis | Secondary (15%) | Secondary (15%) | Matched |
| Forearms & Grip | Secondary (12%) | Secondary (12%) | Matched |
| Shoulders (Deltoids) | Secondary (10%) | Secondary (10%) | Matched |
Load & Volume Conversion: Machine Iso-Lateral High Row → T Bar Row
Worked weight heuristic: a 115 kg set on Machine Iso-Lateral High Row (Machine) maps roughly to 100 kg on T Bar Row (Barbell; 2.5 kg jumps, curve: descending or bell-shaped barbell lever). Calibrate set 1 at RPE 8 so e1RM history for Machine Iso-Lateral High Row remains unskewed. Zero anatomical muscles are dropped between Machine Iso-Lateral High Row and T Bar Row; 1:1 weekly set volume carries straight across.
