In this video, Sanford POWER Coordinator Scott Roggenbuck describes the stability ball test.  Start by sitting on an exercise ball with two dumbells of appropriate weight in both hands, then roll so that the top of your shoulder blades is directly on the ball so that you’re essentially on your back with the dumbells in bench press-like position.  Then, press up the dumbells together in a nice and controlled fashion until your arms are fully extended, then return them back to your chest and repeat 8-12 times, with 3 total sets.  Make sure to maintain your body being parallel to the ground.  This is a great exercise to strengthen your core and to improve overall stability.
