Size of stability ball?

[katia7]

I'm a little over 5'0. Should I get the stability ball that's for people who are 4'7-5'0 (45cm ball) or one for people who are 5'1-5'6 (55cm ball).

Thank you,
Katia

I think you should get the 55cm ball. The true measure is for you to sit on it and have your thighs be parallel to the floor. I figure you can always underinflate the 55cm ball - but it would be dangerous to overinflate the 45cm ball.

I also recommend the 55cm ball. I'm 5' 3/4" and have a 55cm ball which has worked just fine for me.
