hey there. anyone have any experience with the exercise ball thingys? (the really big ones that i hear are really good for back and ab exercises and stuff). they look interesting, but i don't want to run out and get one without some input.
thanks
thanks for the reply. i am thinking i will get a fitball/balance ball/whatever the name is for xmas. i saw a set in a catalog that is the ball, 2 videos for it, and a pump for it for $40, so i may go for that. just looking for more things to do at home that are interesting.
and i really need help with ab and back exercises
