Reverse Flyes with Exercise Ball and dumbbells
Lie face down with the Sissel exercise ball under the abdomen and hips. Extend the legs behind you, feet anchored. Hold dumbbells and position arms in front of the ball. Squeezing the shoulder blades together, extend the arms to either side until the upper arms line up with the shoulders and the hands line up with the top of the ball. At the top of the motion, palms face inward. Release.
