To have any doubt in your body is the biggest weakness an athlete can have. There are times when I physically can't get myself to go for a skill because I'm thinking, 'My knee hurts really bad.'

Hot yoga is the best. When you're in [class], there are no cell phones, no talking, no distractions. You're taking a leave from reality for an hour or so.

My approach to gymnastics in Beijing was heavily based on the amount of difficulty I could do.

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!

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

If you lose the nerves, you lose the sport.
