Core/Abs Exercises

[mountainchick]

Those stability balls -- what do I need to know before I buy one? Something tells me I should know something, because nothing is ever as easy as toss-into-basket/pay/take-home.

Is it?

When I got mine it had height measurements on it for the different sizes. I just picked up one that my height fit into its categories...Otherwise I would have just bought the first one I saw.


Woot woot!! Post 100!!
