How to perform One-Arm Kettlebell Jerk
- Hold a kettlebell by the handle. Clean the kettlebell to your shoulder by extending through the legs and hips as you pull the kettlebell towards your shoulder. Rotate your wrist as you do so, so that the palm faces forward. This will be your starting position.
- Dip your body by bending the knees, keeping your torso upright.
- Immediately reverse direction, driving through the heels, in essence jumping to create momentum. As you do so, press the kettlebell overhead to lockout by extending the arms, using your body's momentum to move the weight. Receive the weight overhead by returning to a squat position underneath the weight. Keeping the weight overhead, return to a standing position.
- Lower the weight to perform the next repetition.

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
- Keep the ribs down and the glutes tight so the lower back doesn't arch to 'help' the weight up.
- 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.
- Breathe out on the effort and in on the return, keeping one steady rhythm across the set.
Common mistakes
- Pressing with the lower back arched instead of a braced, stacked torso.
- 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.
