Stand up on two boxes, mats, or some other elevated surface with space in between your feet to allow room for the kettlebell to move. Set your shoulders down and back, away from your ears. Keep your abdominals braced and a slight bend in your knees.
Inhale deeply through your nose and send the air down deep into your abdomen as you reach your glutes and hamstrings back toward the wall behind you.
Keep spine straight, only hinging at your hips. Squeeze your glutes as you return to the starting position.
