What exactly is a Dynaflex Powerball?
It's a hand-held sphere within a sphere that can provide you with hours of fun as it simultaneously gives your fingers， hands， wrists， forearms， biceps， and triceps a great workout (via its powerful gyroscopic action)!
It's a high-tech portable device and an awesome strength training exerciser (the faster you accelerate the inner sphere， the harder it is to hold on to).
It's a wonderful tool that aids in the prevention and rehabilitation of carpal tunnel or other repetitive strain injuries affecting the wrists.
It's a neat gadget that people can't wait to try after they see it in action. Teenage boys and men especially love the competition that the optional speedmeter attachment provides.
It's a unique and reasonably priced gift that will be used again and again--and thoroughly enjoyed!
If you want a LIGHT or HEAVY workout for your fingers， hands， wrists， arms， biceps and triceps， buy this powerball!
Once this powerball is activated (via the string that comes with it OR your thumb--with some practice)， it starts to glow BLUE. The faster the unit runs， the brighter the lights will be until your whole hand is engulfed in a bright glow. The faster you spin it， the harder it is to hold on to. Pretty soon， your wrists， grip， and arm are straining and working out against a powerhouse gyroscopic action. Need a break? Slow down the rotations， or pass it on to an unsuspecting friend. Watch them try to hold on to it! Use it as an executive relaxer， a carpal tunnel / arthritis reliever， or as a strength and coordination builder. DynaFlex's Powerball blue will knock your socks off!
