Lie face down on a bench or a table with your hips hanging over the edge. One end of an exercise band is secured firmly to the bench/table and the other end around your foot.
Bend your knees and lift your heels close to your buttocks. Straighten your leg against the resistance using your buttock muscles. Keep the other leg bent. In a controlled manner, return to the starting position.
Note: Keep your back in a neutral position (abdominals active).
