Setup

  1. Clean the kettlebell to the rack position, resting the bell in the 'V' of your arm with your elbow tucked tight to your ribs.
  2. Position your feet shoulder-width apart with toes slightly turned out.
  3. Engage your core and glutes to create a stable foundation, keeping your torso upright.

How to do it

  1. Perform a 'first dip' by quickly bending your knees 2-3 inches while keeping your heels down and torso perfectly vertical.
  2. Explosively extend your hips and knees to drive the kettlebell upward, exhaling sharply as the weight leaves your shoulder.
  3. Perform a 'second dip' by quickly dropping your hips under the rising bell, catching it with a fully locked-out arm.
  4. Stand up completely to finish the rep, then lower the kettlebell back to the rack position while inhaling to reset.

Form checklist

  • Keep your torso vertical during the dips; do not lean forward or hinge at the hips.
  • Ensure your elbow is fully locked out before you begin standing up from the second dip.
  • Keep the kettlebell close to your midline rather than letting it drift out to the side.
  • Maintain a neutral wrist throughout the movement to avoid strain.

Pro tips

  • The jerk is a leg-driven movement; your arm should only guide the bell and lock it out, not 'press' it upward.
  • Focus on the 'bump'—the moment your hips transfer energy into the kettlebell—to make the weight feel weightless during the catch phase.

Make it harder

  • Perform the movement with a heavier kettlebell to increase the demand on your core and overhead stability.
  • Incorporate a 2-second pause at the top of the lockout to maximize time under tension for the stabilizing muscles.
