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!'
I do a lot of biking. I need that mileage and the long-distance stuff because tennis demands it. My fitness trainer is always trying to convince me to do an Ironman. I can probably run the marathon, I can make the 112 miles on the bike, but I will never swim for 2.4 miles. I will die after 100 meters.
