Stability Balls

I am thinking about downloading Core Max #2 but I have a stability ball question.

I have been in the Cathe Shop and there are all sorts of size balls there ranging from 55 - 75cm. How do you know what size ball to get? Are there benefits of bigger or smaller ones?

How tall are you? The size of the ball you get depends on your height. I'm just over 5'1 so I have the 55 cm ball. I think if you are over somewhere around 5' 4 you want the next size up. Some of it depends on your body's proportions too, but generally you want to form a 90 degree angle with your legs while seated on the ball. HTH.

Thanks for your help!

I ended up getting one for Christmas so the decision was taken out of my hands but they chose a 75cm once and I think that is perfect (I'm reasonably tall 5' 10"). I live in Australia so my family got the ball from a local sports store rather from Cathe because the shipping cost would have been huge.

My problem now is that the ball is actually more of an oval shape. Are the Cathe ones perfectly round... are they supposed to be perfectly round or is it normal for them to be more oval shaped?
