When I was younger, I would eat everything.

Don't just tell your kids to be active and to get outside and play. Lead by example.

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.

Thinking about your training should put a smile on your face. As cliche as it sounds, you are worth all the time and energy you've put in. Unleash your emotions with a cheer, or even a signature roar, after a tough workout.

I love KIND bars. My favorites are coconut and almond and the dark chocolate and sea salt because staying fueled helps keep me from getting sick or injured. Bananas have also made a great comeback in my life. My kids eat them all the time on the go, which has inspired my go-to pre-run morning meal of peanut butter and banana on toast.

I love to run, but training can be hard, especially with a family and a crazy travel schedule. I often do sprints with my kids, where they bike and I run along side them so we can 'race' each other for a quarter-mile or shorter repeats.

Tennis is interesting because the women are almost more popular than the men. In the U.S. Open, women even get exactly the same money as the men.
