Start by sitting on the floor with legs bent. Lean back so that your lower back and buttocks touch the floor. Straighten your legs close to the floor and straighten your arms overhead so you are in the 'hollow hold' position.
Bend your hips and curl your upper body up. Reach towards your toes with your arms and let your knees bend and bring them towards your chest. Reverse movement to return to starting position (hollow hold position).
