Dyna won't you blow your Ball?

I bought this at a golf convention over in las vegas several years ago. yes, i was there for the conference only... anyway, the power ball caught my eye over all the golf clubs and even as a prototype back then it was immediately attractive. i bought it and started using it to train my forearms. in fact, it's a lot better than the grip strengthening grippies because it take a lot more coordination. you have to feel the torque and work against it. the only moving parts is the rotating gyro inside. the Dynaflex Gyro Ball 9000 rotates at 13,000 RPM and resists from 32 to 35lbs of torque. after about a minute of buzzing, the arms will feel sore and tired, while from the outside people will have no idea why you're cramping up. it's a pretty smart design and definitely portable. i personally find it useful in anything involving the forearm muscles, including any racquet sports, golf, or even guitar. the newer versions come with a glowing LED which is powered by the rotation of the gyros. there are many imitators out there, and i have yet to try them all, but even after 5 years of usage my powerball is still spinning strong.
