I had a constant fear, a constant little doubt in my mind: 'OK, I'm getting ready to do my standing back full on beam and I might re-tear my ACL.'

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.

That's the drama of our sport. Our margin of error is so small that anything can happen.

Gymnastics is so complex.

I always feel like I'm the young one, I'm the small one.

I have a chaperone everywhere I go - my mom.

After 13 years of hard landings in gymnastics, one ski run had delivered the biggest injury of my career.
