How to Perform

Stand with feet wider than shoulders, toes out. Place kettlebell on floor in front. Hinge at hips to grip with one hand, back flat, core braced.

  2. Explode hips forward to swing kettlebell to chest height.
  3. At peak, release and catch with opposite hand smoothly.
  4. Allow kettlebell to descend, hinging hips for next backswing.
  5. Drive hips forward again with new hand.
  6. Repeat alternating hands in continuous rhythm.
