At the end of a marathon, it's going to hurt whether you're speeding up or slowing down. You may as well push.

Here's what I've learned about eating healthy when you're busy: It's all about preparation. Make your snacks on Sunday, and you will be good to go until Thursday or so.

It's the one thing that's mine. My runs everyday aremy thing. It's my therapy, my hour to myself. Nobody can really take it away from me... It's such a huge part of me. I love to say that I'm a runner.

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.

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.

Daily repetition matters when a kid is learning to swim. It can be 20 minutes in a lesson or an hour practicing for a couple of weeks.
