How to Perform

Stand with feet wider than shoulder-width, toes slightly outward. Hold kettlebell by horns against chest with elbows tucked in and core braced.

  1. Shift weight to one side and bend the knee of the working leg.
  2. Squat down deeply while extending the other leg straight laterally.
  3. Rotate the extended leg so toes point up and heel stays down.
  4. Maintain upright torso and pause at bottom for stretch.
  5. Drive through working heel to extend knee and hip back to start.
  6. Transition smoothly to opposite side keeping hips low.

Coaching Tips

Form Cues

  • Chest up tall
  • Knee tracks over toes
  • Heel planted firm
  • Core engaged tight
  • Hips low transition

Breathing

Inhale during descent into the squat, exhale as you drive up. Brace core on every rep.

Tempo

3-1-2

Range of Motion

Descend until working thigh is parallel to floor or deeper if mobility allows, with inner thigh of extended leg fully stretched; extend fully to wide stance at top.

Safety

Safety Notes

  • Avoid forcing depth beyond mobility limits
  • Consult professional for hip or knee issues
  • Start with bodyweight if new to movement
  • Keep controlled speed to prevent joint strain
  • Ensure stable surface for extended leg

Spotting

Spotting not typically required; assist with hands on hips for balance if beginner, or use rack for support.

Common Mistakes

  • Rounding lower back
  • Leaning torso forward
  • Knee caving inward
  • Heel lifting off ground
  • Rushing the descent

When to Avoid

  • Acute hip impingement
  • Knee joint instability
  • Recent lower back injury

Flexibility Needed

  • Adequate hip abduction range
  • Sufficient ankle dorsiflexion
  • Thoracic spine extension

Build Up First

  • Proficiency in bodyweight Cossack squat
  • Comfort with lateral lunges
  • Basic squat form mastery
