ShoulderSphere F2

Pre-Black Friday and Cyber Monday Gift Sale!!! Most suitable for those individuals who want to maintain a healthy and strong shoulder/rotator cuff for recreational sports and daily activities.   Particularly beneficial for young competitive athletes to enhance their performance and prevention of shoulder/rotator cuff injury.  The F2 model is also a perfect adjunct for use under the guidance of a physical therapist in aiding shoulder/rotator cuff recovery from injury or surgery. The Personalized Electronic Tracker tracks in real-time with continuous feedback of the power output by the shoulder/rotator cuff during use.  For example, while moving the arm as if throwing a ball, but while keeping the Tracker light in Red, corresponds to the power behind the throw of a tennis ball 60 mph from the tennis court baseline to the tennis net.  Keeping it in Green corresponds to the power behind a 40 mph tennis ball throw from baseline to the net.  Train for shoulder/rotator cuff stamina and control by maintaining in the Green for 3 reps of 90 second workouts every other day!  Train in a Red for strength.
