Today I found that you can get a “Powerball” for under £20! They are said to really help to improve many different sporting activities and general fitness. As I am a keen indoor rower I think it may make a difference to my rowing stroke when working out on the concept two indoor rowing machine. Once I'm up and running with my gym membership through work I can put it to the test and let you know if I’ve seen any improvement on my personal best rowing times.

The Powerball requires no batteries, has no motor and works solely off of “gyroscopic” power. It just requires spinning your wrist while held tight in your hand to start the device off, the Powerball can then get up to spinning 15,000rpm at which point it's exerting almost 40lbs of pressure on your limbs and is travelling at nearly 250 revolutions per second.

You can use a Powerball as a fitness product to either tone or help build substantial power and strength in the wrists, forearms and shoulders. The Powerball is also a great rehabilitation product to mobilise and gently rehabilitate the lower forearm arm.
