Equipment

Setup

  1. Stand with feet hip-width apart, holding a kettlebell by the horns in a goblet position at chest height.
  2. Shift your weight onto the working leg and lift the non-working leg slightly off the floor in front of you.
  3. Engage your core and pull your shoulder blades back and down to create a stable shelf for the weight.

How to do it

  1. Inhale and slowly lower your hips back and down while simultaneously extending the non-working leg straight out in front of you.
  2. Descend with control until your hip crease is below the knee of the working leg, using the kettlebell as a counterweight.
  3. Exhale and drive forcefully through the mid-foot of the working leg to return to a full standing position.
  4. Perform the desired number of repetitions on one leg before switching to the other.

Form checklist

  • Keep the heel of the working foot firmly planted on the ground throughout the movement.
  • Maintain a tall chest and avoid excessive rounding of the lower back at the bottom of the squat.
  • Ensure the working knee tracks in line with your toes and does not cave inward (valgus).
  • Keep the non-working leg fully extended and elevated to avoid touching the floor.

Pro tips

  • Slightly pushing the kettlebell away from your chest during the descent can act as a counterweight to help you stay upright if you have limited ankle mobility.
  • Focus on 'rooting' your foot into the floor by gripping with your toes to maximize balance and power output.

Make it harder

  • Increase the weight of the kettlebell or hold it in a front-rack position on the side of the working leg.
  • Implement a 3-second eccentric (lowering) phase to increase time under tension and demand more stability.
