[b]NO NOT THOSE BALLS![/b]...You ever use them......[b]correctly?[/b]Not the small medicine ball, the larger balls called 'sissel' I think.THESE THINGS KILL![kill]The NFL is using them now....guys do pushups on'em,SQUATS STANDING ON TOP OF THE BALL!.....there are a many killer core balance/strength'n'ing exercises that are now being used by the pro-athletes(they get paid for better preformance I'd think).....I found the site....[url]sissel-online.com[/url]This is the most difficult workout type I've ever tried.Look at the catagories section.It concentrates on total body balance and muscle coordination and interaction.

a guy i know who teaches a LEO technique known as groundfighting to the RCMP and other police agencies told me about those things, and this guy can pop a fucking BASKETBALL with his abs, so there must be something to it.

Found the site...your right EdAvSr those pushups are on this site too.And I tried them once....I'll stick to the weights........I have bad wrists
