Setup
- Stand facing a sturdy box or bench with your feet hip-width apart and arms at your sides.
- Select a box height that allows your thigh to be approximately parallel to the floor when your foot is placed on top.
- Engage your core and maintain a neutral spine with your gaze forward.
How to do it
- Place your entire right foot firmly on the box, ensuring your heel is not hanging off the edge.
- Exhale as you drive through your right heel to extend your hip and knee, bringing your left foot up to meet the right on the box.
- Inhale as you slowly step back down with the left foot, followed by the right, controlling the descent to avoid a hard landing.
- Repeat the movement by leading with the left foot, alternating sides for the duration of the set.
Form checklist
- Keep your chest upright and avoid leaning excessively forward.
- Ensure the knee of the working leg stays aligned with your second toe, avoiding internal collapse.
- Avoid pushing off the floor with your trailing foot; let the lead leg do all the work.
- Maintain a level pelvis throughout the step to ensure even muscle engagement.
Pro tips
- To maximize glute recruitment, lean your torso slightly forward (about 10-15 degrees) while keeping your back flat.
- Focus on a slow, 3-second eccentric (lowering) phase to increase time under tension and improve stability.
Make it harder
- Increase the box height to challenge your range of motion and hip mobility.
- Add a high-knee drive with the trailing leg at the top of the movement to further challenge balance and core stability.
