To perform this action correctly, the muscles involved are the hip flexors, hip extensors, gluteal muscles, hamstrings, and calf muscles. The hip flexors allow you to lift the right hand and roll your head, while the hip extensors help you bend your right leg and keep your legs extended. The glutes and hamstrings help you extend your legs and move your toes outward. Lastly, the calves contract to allow the heels to move toward the middle and the toes to point outward.
