For the serious competitive athletes who need not just power; but power with control, these personalized collapsible Coaching Rings are easily portable  in gym bags.  This attractive and ergonomically designed accessory ensures an amazing and disciplined workout anywhere for a focused high intensity exercise that trains your shoulder/rotator cuff for both power and control. Dynamically move the arm while spinning the ball to pass through the Coaching Rings requires intense focus and power with control. A great training tool for those movements during competition that require concentration, power, and control. The Purple Ring is entry level while the Blue Ring is a challenge!  A pass through the Ring back and forth for 20 reps equals a one minute workout with a highly focused intensity!   In order to pass through the Blue Ring with the ShoulderSphere A7 model, the user must have the power equivalent in the shoulder/rotator cuff behind a 90 mph baseball pitch, or a 25 mph heavyweight boxer's punch.  A must have for any serious athlete!  A ShoulderSphere F2 model passing through the Blue Ring equates to the power behind throwing a tennis ball at 60 mph from the baseline to the tennis net.
