Hi,
I have had a look at the powerballs and I am confused, I am not sure how they work and how to perform the exercises. Could someone please tell me a quick info about these powerballs and the benefits so to give me an insight weather to buy them or not?
I'm sure there was a thread with some info in it but I can't find it at the moment.
Powerballs are designed to help improve grip (and possibly wrist strength) but they also work the arm and shoulder to some extent. They were the big thing with golfers a few years as well as a few other sports.
From what I understand, they work by feedback - you have to 'hold' the ball whilst the gyro spins and creates force. The smaller the movement the faster the ball goes and the more force is created.
They're pretty good for wrist/arm rehab by all accounts.
Have a look here - http://www.powerballs.com/ as I sure it can give you more info than I can. There are also some videos on there which should illustrate how it works.
