FITNESS Olympics Special: Eight Olympic Athletes in '08

Shawn Johnson: "I am... focused."

Age: 16
Sport: Gymnastics
Hometown: West Des Moines, Iowa
Training: Four hours a day during the week; five or six hours on Saturday. Sunday is a rest day.
Olympian tip: Right before a competition, Shawn visualizes herself completing a perfect routine. She finds that the mental imagery transfers to her actual performance.

"Being one of the youngest Olympians has its pros and cons. I bring spirit and energy to the sport, and I'm proud of what I've accomplished. But I've had to deal with responsibilities that most people don't encounter until they're older. I use the pressure of the Games to fuel my motivation and work even harder. Being an athlete is about so much more than physical fitness -- it teaches you to stretch your mind and push the limits of what you can achieve."
