Setup
- Stand sideways next to a step or low platform with feet hip-width apart.
- Raise both arms straight overhead, keeping your shoulders depressed and away from your ears.
- Engage your core and maintain a tall, neutral spine.
How to do it
- Step your inside foot firmly onto the center of the step, ensuring the entire foot is supported.
- Exhale as you push through the heel to lift your body, simultaneously rotating your torso toward the stepping leg.
- Briefly balance at the top with the trailing leg hovering, then inhale as you step back down with control.
- Perform all reps on one side or alternate sides by stepping over the platform.
Form checklist
- Keep arms extended and stationary relative to the shoulders to ensure rotation comes from the core.
- Ensure the knee of the stepping leg tracks directly over the toes without caving inward.
- Maintain a braced midsection to prevent arching the lower back while arms are raised.
- Keep your chest lifted and eyes forward throughout the rotation.
Pro tips
- Focus on 'wringing out' your waist as you step up to maximize oblique activation.
- Drive through the heel of the elevated foot to better engage the glutes and protect the knee joint.
- Maintain a slow, controlled tempo on the way down to increase time under tension for the quadriceps.
Make it harder
- Increase the height of the step to increase the range of motion and glute demand.
- Hold a light medicine ball or water bottle between your hands to increase the rotational inertia.
