HOW: In a standing position, shift your weight to one leg. Bend that knee and reach out to the side as far as you can comfortably go and tap your toe. Stay balanced on the one leg as you bring the leg back and reach behind you as far as you can go. Return to the starting position and repeat for the prescribed amount of reps.
FEEL: You should feel your hip and lower leg muscles working.
COMPENSATION: Try to keep your chest facing forward as you reach to each side.
