Seated Horizontal Leg Press — Muscles Worked & RPE Load Guide
Seated Horizontal Leg Press targets Quadriceps, Glutes as primary movers (1.0× set credit) alongside Hip Adductors, Hamstrings (0.5× synergist credit). Cam-matched resistance across sticking points.
17-Muscle Fractional Recruitment & Weekly MEV–MRV Landmarks
Each working set ≥ RPE 6 triggers fractional hard-set credit toward Renaissance Periodization / Schoenfeld weekly hypertrophy landmarks.
| Muscle Group | Mechanical Role | Effort Share | Weekly Optimal Band (MEV–MAV) | Frequency & Research |
|---|---|---|---|---|
| Quadriceps | Primary (1.0× set) | 55% | 8–18 sets/wk (MRV 20) | 2–4x / week · Evidence |
| Glutes (Gluteus Maximus / Medius) | Primary (1.0× set) | 28% | 4–16 sets/wk (MRV 20) | 2–4x / week · Evidence |
| Hip Adductors | Secondary (0.5× set) | 10% | 4–12 sets/wk (MRV 16) | 2–4x / week · Evidence |
| Hamstrings | Secondary (0.5× set) | 7% | 4–16 sets/wk (MRV 20) | 2–4x / week · Evidence |
