Setup
- Stand facing a sturdy box or bench with a dumbbell in each hand, held at your sides with a neutral grip.
- Position your feet hip-width apart and pull your shoulders back to set a tall, upright posture.
- Ensure the box height allows your lead knee to be at roughly a 90-degree angle when your foot is planted on top.
How to do it
- Step your lead foot firmly onto the center of the box and drive through the heel to lift your body upward, exhaling during the exertion.
- Instead of standing on top, swing your trailing leg completely over the box and step down onto the floor on the opposite side.
- Control your descent slowly, inhaling as you lower your trailing foot to the ground to avoid a hard impact.
- Turn around and repeat the movement starting with the opposite leg to return to the starting position, alternating sides each rep.
Form checklist
- Keep your chest up and gaze forward to maintain a neutral spine.
- Avoid 'pushing off' with the toes of your trailing leg; let the lead leg do the work.
- Ensure the knee of your lead leg stays tracked over your mid-foot, not caving inward.
- Maintain a tight core to prevent the dumbbells from swinging during the transition over the box.
Pro tips
- Focus on the 'negative' phase by slowing down the descent on the far side of the box to maximize eccentric muscle damage and growth.
- Keep the dumbbells perfectly still at your sides to challenge your lateral stability and grip strength throughout the movement.
Make it harder
- Increase the box height to deepen the hip flexion and increase glute activation.
- Hold the dumbbells in a front-rack position at your shoulders to shift the center of mass and increase the demand on your core and quads.
