I need to get an exercise ball that is 45 cm. I can find the 55, 65, etc. ones at Wal-Mart and Target, but not a 45 cm. Does anyone know of any stores they would recommend beyond Wal-Mart and Target. I also tried Sports Authority, and they didn't have a 45 cm ball. I may just have to order one off of Amazon, but I'd like to see it in person before I get it.

I'm in (Palo Alto/Mountain View) the SF bay area.

P.S. The reason why I want one that small is that the fitness instructor I've been going to has me doing several exercises using a smaller one. For my height, the 55 cm one is best for most all other exercises.

amazon has one for $13, put 45cm exercise ball in the search and it will pop up!

Yep, Amazon has quite a few available, but none that are eligible to be shipped via Amazon Prime and I'd like to get one here locally. Thanks though.
