The body is an amazing machine... If you eat the right things your body will perform incredibly well!

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.

It's nearly every country's tactic to keep their greatest competitors a secret.

When I was younger, my coach, Liang Chow, made all the decisions. I would go to the gym for practice, do exactly what Chow told me to do, go home, come back and start all over again. If Chow told me to do 50 squat jumps, I did 50 squat jumps.

I love lean meats like chicken, turkey. I'm obsessed with sushi and fish in general. I eat a lot of veggies and hummus.

Everything for me started with my love of the sport. In society we're losing the fun with kids and pushing success on them too hard. Success comes from fun.

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.
