Seated Horizontal Leg Press vs V Squat Machine
Swapping Seated Horizontal Leg Press (Machine) for V Squat Machine (Machine) retains 100% overlap; expect externally braced cam track. 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 Seated Horizontal Leg Press for V Squat Machine.
| Muscle Group | Seated Horizontal Leg Press | V Squat Machine | Leverage Shift |
|---|---|---|---|
| Quadriceps | Primary (55%) | Primary (55%) | Matched |
| Glutes (Gluteus Maximus / Medius) | Primary (28%) | Primary (28%) | Matched |
| Hip Adductors | Secondary (10%) | Secondary (10%) | Matched |
| Hamstrings | Secondary (7%) | Secondary (7%) | Matched |
Load & Volume Conversion: Seated Horizontal Leg Press → V Squat Machine
Worked weight heuristic: a 115 kg set on Seated Horizontal Leg Press (Machine) maps roughly to 115 kg on V Squat Machine (Machine; 5 kg jumps, curve: cam-matched resistance across sticking points). Calibrate set 1 at RPE 8 so e1RM history for Seated Horizontal Leg Press remains unskewed. Zero anatomical muscles are dropped between Seated Horizontal Leg Press and V Squat Machine; 1:1 weekly set volume carries straight across.
