Thumbs Up Arm Raise!
Strengthen your upper back muscles with this exercise on the ball. A strong back means standing up straight for longer, and with greater ease. Here’s how:
Lie on a stability ball face down with your feet flat on the floor wide for balance. Lift your chest away from the ball so your body is straight and core is stable. Extend both arms straight down toward the floor. Next rotate your palms forward so your thumbs point up. Lift and lower your arms. Perform 10-15 reps.
*Consult your physician before beginning exercise.
