I started from zero and went back to the basics in gymnastics.

I think about my goals. There were a lot of times in gymnastics when I really didn't want to go in and train, but you can't make it to the Olympics if you don't train!

It might have been easier to retire, to say my knee couldn't handle it and let that be that. At the same time, the prospect of not being able to compete in gymnastics anymore was heartbreaking.

I don't call them sacrifices. I call them exchanges.

It sounds funny, but the 2008 Olympics were something that just kind of happened, and I was lucky they came at a point when I was uninjured and well prepared. As a gymnast, you can't ask for much more.

I was always trying to be leaner and thinner to fit the standard and the mold.

Gymnastics has made me strong. I feel like it broke me down to my lowest point, but at the same time, it has given me the greatest strength anyone could ask for.
