HOW: Start in a standing position with your feet together and a slight bend in both knees. Slightly hinge forward at the waist and cross your arms across your chest with your hands on your shoulders. From here, turn your hips from side to side while keeping your upper body still or lifting your feet up. Turn to each side for the prescribed amount of reps.
FEEL: You should feel a stretch in your hip muscles as you go back and forth.
COMPENSATION: Keep your feet and upper body still, only move your hips.
