Sit on your stability ball and slowly walk feet away from you to where your shoulder blades, back and hips are balanced on the stability ball. Keep your knees about shoulder width apart, bent at 90 degrees.
Bring your arms overhead and bring your belly button in towards your spine. Next, bring your arms over your shoulders while elevating your chest so that your upper back and shoulder blades come off the stability ball. Hold for 5 seconds and then return to the starting position. Let’s to 4 sets of 10!
When this becomes too easy, grab a 2-5 pound dumbbell and hold the weight with both hands while elevating your upper body off the ball.
