The "it" girl
LINDSEY VONN, 25, ALPINE SKI RACER
Last season Lindsey nabbed her second consecutive overall World Cup championship and became the winningest female American skier in history. The gold-medal favorite in four Alpine events, she credits her best friends with keeping her motivated; "They wear 'Vonntourage' sweatshirts at my races and work out with me to make training fun."
ON STAYING COOL UNDER PRESSURE "Before a race, I play a game like Brain Age on my Nintendo DS."
FUEL-UP ADVICE "I start the day with a big bowl of muesli. It helps me power through my a.m. workout."
HER BEST TRAINING TIP "I swear by this core move: Sit on a stability ball with your feet on the floor and have a friend toss a weighted ball to you. Catch it as you lean back, then throw it to her as you crunch up."
