Setup
- Place a step box or low platform on a flat, stable surface.
- Stand sideways to the box and place your right foot firmly in the center of the step.
- Position your left foot on the floor, roughly hip-width apart from the box, with toes pointing forward.
- Stand tall with your core engaged and hands held in front of your chest for balance.
How to do it
- Inhale as you lower your hips back and down into a squat, keeping your chest upright and weight distributed across both legs.
- Descend until your thighs are at least parallel to the floor, ensuring the knee on the box tracks in line with your toes.
- Exhale as you drive through both feet—specifically pushing through the heel of the elevated foot—to return to the starting position.
- 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.
