HOW: Begin by lying on your stomach with your arms straight out to the side. Keep your upper half on the ground as you lift one leg up and over the other leg tapping the toe, and returning. Alternate each leg going back and forth for the prescribed amount of reps.
FEEL: You should feel your low back and hips stretch.
COMPENSATION: Try to keep from your belly button up on the ground as you twist up and over with each leg.
