ive just bught one of those ab rollers the ones where u stand up and push it along the floor until ure horizontal and then pull yourself upright.Im wondering if any of u guys have tried them and if so what are your views? it seems to be a killer on the abs and arms.
cheers karky ive just checked out your link and im not quite goimg down as far as the guy. But i am in control of my whole movement i guess ill start on my knees and get my form spot on.
