Setup

  1. Place a step box or low platform on a flat, stable surface.
  2. Stand sideways to the box and place your right foot firmly in the center of the step.
  3. Position your left foot on the floor, roughly hip-width apart from the box, with toes pointing forward.
  4. Stand tall with your core engaged and hands held in front of your chest for balance.

How to do it

  1. Inhale as you lower your hips back and down into a squat, keeping your chest upright and weight distributed across both legs.
  2. Descend until your thighs are at least parallel to the floor, ensuring the knee on the box tracks in line with your toes.
  3. Exhale as you drive through both feet—specifically pushing through the heel of the elevated foot—to return to the starting position.
  4. Perform the desired number of repetitions on one side before switching to the other leg.

Form checklist

  • Keep the knee of the elevated leg from caving inward during the descent.
  • Maintain a neutral spine and avoid rounding your lower back at the bottom of the movement.
  • Ensure both heels remain in contact with their respective surfaces throughout the entire rep.
  • Keep your shoulders back and down to prevent leaning too far forward.

Pro tips

  • Focus on the 'mind-muscle connection' by consciously driving the elevated knee outward to maximize gluteus medius engagement.
  • Pause for one second at the bottom of the squat to eliminate momentum and increase time under tension.

Make it harder

  • Hold a dumbbell or kettlebell in a goblet position at chest height to increase resistance.
  • Increase the height of the step box to deepen the squat and increase the eccentric stretch on the glutes.
