How to perform Kettlebell Swing
- Stand with feet shoulder-width, kettlebell on the floor in front.
- Hinge at the hips and grip the kettlebell with both hands.
- Hike it back between your legs, then snap your hips forward.
- Let the bell float to chest height, then guide it back down.
Muscles worked
- Hamstrings (primary): bends the knee and extends the hip through hinges and pulls.
- Glutes (secondary): extends and stabilises the hip — the engine behind hinges, squats and sprints.
- Back (secondary): pulls the arms down and toward the torso and keeps the spine stable.
- Core (secondary): braces the trunk and resists twisting to protect the spine.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Lead with the hips, keep a soft knee and hold a long, flat back through the hinge.
- Let the bell stay close to your body and grip only as hard as you need to keep the wrist neutral.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Control the lowering phase — a 2–3 second descent builds more than dropping the weight.
Common mistakes
- Rounding the lower back to reach lower instead of hinging at the hips.
- Gripping the bell in a death-grip, which burns out the forearms long before the target muscle.
- Chasing weight jumps before the current load feels solid on every rep.
