Lie on the floor on your back. Bend your knees and put your feet flat on the ground. Press your hands into the floor. Initiate movement by lifting your right foot off the floor and bringing it towards your chest. Push your left foot into the floor and drive your hips and glutes up until you reach full hip extension. Straighten your right leg, creating a straight line from your leg all the way to your shoulders. Squeeze your glutes at the top of the movement and slowly return to starting position. Bring your left leg to your chest and repeat with the other side.
