Ali C Posted August 27, 2007 Report Share Posted August 27, 2007 No i ahve never tried one wouldn't waste my money either i go to the gym for building muscle you cant really comment if you havnt tried one, its not just the movments, the gyroscopic movment inside the ball can get up to the equivelent of 30lbs (or somthing like that) try getting a bike wheel, spinning it and then twist it with your hands, its hard, the powerball is the same, but smaller and lighter.Also, £12 is a wee bit cheaper than going to a gym and it can be done while watching tv or somthing.I got bored of mine though, it gives me blisters on my little fingers (my best was 12000 though) Quote Link to comment Share on other sites More sharing options...
