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

I have a fit ball and love it! Just make sure you get the right size for your height.

How do you know what the right size is exactly?

I got this information off of http://www.fitball.com

When sitting on the ball, your knees and hips should be at 90 degree angles or slightly higher. Here are some general guidelines:

4'8" to 5'3" 55cm
5'3" to 6'0" 65cm
6'0" to 6'7" 75cm

I have the 65cm ball (I'm 5'4 and my husband is 5'9). Hope this info helps.

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
