Alright all,
I just had my first run through of the thoracic bridge stretch course, but equipment was lacking. I was wondering what size theraball most people go for? I expect this is height dependant and I'm 6'5" so would probably need a relatively larger one. I currently have a 65cm ball which is obviously way too small, so if anyone of a like size can provide some guidance before I head off and buy one that would be appreciated.
Thanks,
Martyn.
