Lay securely on the stability ball, with your your hips in the air.
Grasp a dumbbell in each arm with an overhand grip. Your palms will face each other
as you bring the weights up above your chest. You arms have a slight bend in the
elbow but are facing straight up.
Lower the dumbbells down to either side at the same time. Go down far enough to feel
a slight stretch in the pectorals.
Hold for 1-2 seconds and the press back up maintaining the same arc motion.
Tips
Do not stretch too far down, just enough to feel some tension. Contract your
pectorals at the top of the motion.
