Input:
One of the more versatile wrist/elbow/shoulder exerciser. I appreciated the booklet that contained a number of exercises --- and assumed if I register with Thera-Band Acacademy website I'd be able to see all the other exercises possible with the Flexbar.

A difference I see compared to the usual wrist strengthening exercises using resistance bands, is that you get to use your grip while giving your wrist a workout.

What sets the Flexbar apart are the four exercises included in the instruction manual using just the wrist strength to bend the bar to a U four ways: Supination (http://www.thera-bandacademy.com/tba-exercise/thera-band-flexbar-supination), Pronation (http://www.thera-bandacademy.com/tba-exercise/thera-band-flexbar-wrist-pronation), Radial Deviation (http://www.thera-bandacademy.com/tba-exercise/thera-band-flexbar-wrist-radial-deviation), and Ulnar Deviation (http://www.thera-bandacademy.com/tba-exercise/thera-band-flexbar-wrist-ulnar-deviation)
