I always hear about this testing pool. The USADA testing pool that all the fighters are in. Where are they based and what exactly are they testing for? Are they seeing for how long they can keep back stroke? Does it give an accurate measure on cardiovascular endurance? How come I have never seen anyone post pictures of the USADA pool? Is it Olympic sized? How can all the fighters be in there at once all at the same time? If someone has any pics, will be much appreciated. Why did the UFC invest so much into a thrid party pool? Why didn't they just build their own at the UFC performance institute? Or even perhaps donate to the Joe Rogan University?
