I'm really conscious of the amount of food I eat, but I don't deny myself anything. For example, I have a really big sweet tooth. At the end of the night, if I'm craving ice cream, I might not have the bowl that I would have when I was a kid, but I'll put a couple of scoops in a coffee mug, and I'll eat it slowly, and I enjoy every moment of it.

You can't go wrong with some nuts. The key word is 'some.' Eat them one at a time, not by the handful.

I lead by example. My kids know what sweat is. They've seen me come home from so many runs and asked, 'What's on your skin? How did you get it?' And I tell them, 'It's from exercise!' So now my son will come home from a bike ride, take off his helmet and say, 'Look, Mom. I'm sweating! I just worked out!'

A great way to get all the right nutrients is to make a colorful plate - mix of good vegetables, carbohydrates, and protein. If you notice all your vegetables are green, change it up and add another color for a variety of benefits in one meal.

I don't care how much you're working out; when you go to put on that bikini, you're like, 'Oh no!'

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.

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.
