I started swimming when I was four because my brother wanted to join a swim team, and I wanted to do what he did. They said I had to be six, but if I could swim a lap, then I could participate. So I swam a lap, and the rest is history.

When I was training for the Olympics, I didn't eat the way I should have. I missed out on much-needed protein and opted for every easy carb.

Quite simply, my diet has and will always be everything in moderation. People look at Olympic athletes and think they must cut out all those things everyone else indulges in, and speaking for myself, I never did.

I enjoyed every bit of my swimming career. I think that's the most important advice - to enjoy what you do

Swimming is great because there are levels of goals. First, when I was four, it was making it to the other end and overcoming the fear of standing up in front of everybody at a swim meet because I was such a shy kid.

Preparing mentally takes more out of you than the physical aspect of it.

The kids know what I'm doing when I exercise, and that's powerful. So don't just tell your kids to go play outside. Take a moment off your computer, put on your tennis shoes, hop outside and help them start their game and run off some energy.
