• Lie with stomach on stability ball and light dumbbells in hands

• Keeping arms straight, raise dumbbells to front, side and rear for one complete repetition

Form Matters: “Move the dumbbells with control. Don’t swing them with momentum
created by the stability ball. Flex your glutes and abs to provide a stable base, or you’ll end up falling all over the place.”

Why he does it: “This combination works all ranges of motion of the shoulder joint; it strengthens the anterior (front), medial (side) and posterior (rear) delts. Your upper back muscles, including the rhomboids, are strengthened as well. The stability ball works core stabilization.”
