How to Perform

Clean one or two kettlebells to front rack position with feet hip-width apart, elbows tucked, core braced, and chest up.

  1. Inhale and squat down by bending hips and knees until thighs are parallel to floor, keeping back straight and knees tracking over toes.
  2. Explosively drive up through heels, extending hips and knees fully.
  3. Use leg momentum to press kettlebells overhead, locking arms with biceps by ears.
  4. Squeeze glutes and brace core at top.
  5. Control kettlebells back to rack as you descend into next squat.
  6. Repeat for reps.

Safety

Safety Notes

  • Avoid if acute shoulder or wrist pain
  • Master clean, squat, and press first
  • Start with light weight to perfect form
  • Keep heels down to avoid balance loss

Spotting

Not typically needed; use lighter weights or safeties if progressing heavy loads.

Common Mistakes

When to Avoid

  • Shoulder impingement
  • Lower back issues
  • Wrist instability

Flexibility Needed
