A gymnast is performing her routine on the balance beam. She is standing on her left leg and facing forward along the long axis of the beam. Her right leg is flexed 90 degrees at the hip and with the knee extended. Her left arm is fully abducted 180 degrees at the shoulder, and her right arm is abducted 120 degrees at the right shoulder. She begins to fall to the right. What should she do with her arms to help regain her balance?
