Setup
- Stand with your back to a sturdy box or bench, with your heels about 3-6 inches away from the base.
- Lift one leg off the floor, extending it straight out in front of you with your toes pointed up.
- Extend your arms straight out in front of your chest to act as a counterweight.
- Engage your core and find a focal point on the floor 5-10 feet in front of you for balance.
How to do it
- Inhale and begin the descent by hinging your hips back and bending the standing knee simultaneously.
- Lower yourself with control for a 2-3 second tempo until your glutes lightly touch the box.
- Exhale and drive forcefully through the heel of the standing foot to return to the starting position.
- Maintain tension at the bottom; do not fully sit down or relax your weight onto the box.
Form checklist
- Keep the heel of the working foot firmly planted on the ground at all times.
- Ensure the knee of the working leg tracks directly over the middle toes, avoiding internal collapse.
- Keep your chest as upright as possible to prevent excessive forward leaning.
- Keep the non-working leg fully extended and off the floor throughout the entire set.
Pro tips
- Focus on 'soft-touch' mechanics: imagine the box is made of glass and you are trying not to break it.
- If you struggle with balance, hold a light weight (5-10 lbs) in your hands; the forward reach acts as a more effective counterweight than bodyweight alone.
Make it harder
- Decrease the height of the box gradually to increase the range of motion.
- Add a 'pause-and-go' at the bottom, hovering one inch above the box for 2 seconds before standing up.
