I'm doing four hours of gymnastics training a day, six days a week and then an extra two to three hours in a fitness center as well.

It's been strange and weird watching the other girls at the U.S. Olympic trials just because I was training to be out there myself.

When it comes to gymnastics, you can be 30 points ahead going into that competition, but on that day, it's all about luck. It's about who has a good day, who stays healthy, it's how happy the judges are that day, there are so many different factors.

My coach, Liang Chow, had one rule while I was training for the 2008 Olympics: no skiing. I could do anything I wanted outside the gym, he said, except ski.

Gymnastics is so complex.

To have any doubt in your body is the biggest weakness an athlete can have.

I have a healthy lifestyle, but there's nothing you can really do to prevent from rolling an ankle or something like that.
