Stand with your feet together about a foot behind a stability ball. Hinge at your hips and place your hands on the ball. As you keep your posture, raise your left leg behind you until it's parallel to the floor. Keep your foot flexed and inner thigh facing the floor. Rotate your torso to the left and extend your left arm overhead as you gaze up toward the ceiling. Hold for a few counts, return to start and repeat on the other side.
