When I was 3 my parents put me in gymnastics because I was a bundle of energy and they just didn't know what to do with me! They put me in a Tots class and I just fell in love with it.

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.

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

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

I had surgery to repair the ACL in February 2010 and was back in the gym by June, but rushed things too quickly and ended up re-tearing my MCL in September.

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.

I was always known as that stocky, muscular, powerful, short, athlete. People always wondered if I was on steroids, and it was because I wasn't that long and lean, flexible, artistic gymnast. It didn't affect me too much but it got to the point where I tried to be that long and lean gymnast, and it just wasn't possible.
