Lie on your back, and pull your knees into your chest. Reach your legs up to the ceiling, and tightly squeeze them together, focusing on connecting your inner thighs. Reach the legs over to the right, allowing the hips to lift away from the floor. Reach the legs back to center but still engaged, ensuring that the lower back remains on the floor. Reach the legs over to the left, grounding the shoulders and allowing the hips to move first, the rib cage if possible next. Pull the legs back up in toward the body. This counts as one rep. Repeat 10 times.
