Kettlebell swing — Muscles Worked & RPE Load Guide
Kettlebell swing targets Hamstrings, Glutes as primary movers (1.0× set credit) alongside Lower Back, Forearms & Grip (0.5× synergist credit). Ballistic deceleration & grip endurance.
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 |
|---|---|---|---|---|
| Hamstrings | Primary (1.0× set) | 42% | 4–16 sets/wk (MRV 20) | 2–4x / week · Evidence |
| Glutes (Gluteus Maximus / Medius) | Primary (1.0× set) | 30% | 4–16 sets/wk (MRV 20) | 2–4x / week · Evidence |
| Lower Back (Spinal Erectors) | Secondary (0.5× set) | 18% | 4–10 sets/wk (MRV 14) | 1–3x / week · Evidence |
| Forearms & Grip | Secondary (0.5× set) | 10% | 4–16 sets/wk (MRV 20) | 2–6x / week · Evidence |
