Setup
- Place two stepboxes or aerobic platforms parallel to each other, wide enough to accommodate a wide sumo stance.
- Stand with one foot on each box, toes pointed outward at approximately 45 degrees.
- Hold a kettlebell by the handle with both hands, allowing it to hang straight down between your legs.
- Engage your core and pull your shoulder blades back to maintain a tall, upright posture.
How to do it
- Inhale and lower your hips by bending at the knees and hips, keeping your torso as vertical as possible.
- Continue the descent until the kettlebell passes below the level of the boxes, ensuring your knees track in line with your toes.
- Exhale and drive through your heels to return to the starting position, focusing on squeezing your glutes at the top.
- Maintain a controlled tempo, taking 3 seconds to descend and 1 second to drive back up.
Form checklist
- Keep your chest up and avoid leaning excessively forward.
- Do not allow your knees to collapse inward; push them out toward your pinky toes.
- Ensure your heels stay glued to the boxes throughout the entire movement.
- Maintain a neutral spine and avoid rounding the lower back at the bottom of the range.
Pro tips
- Imagine 'tearing the floor apart' with your feet as you descend to maximize engagement of the glutes and hip stabilizers.
- Focus on the deep stretch in the inner thighs at the bottom to fully utilize the deficit created by the boxes.
Make it harder
- Perform 1.5 reps by adding a half-way pulse at the bottom of each repetition.
- Increase the deficit by using higher boxes or stacking platforms to further extend the range of motion.
