The up-and-comer


Katherine's accolades have piled up this season: She grabbed six World Cup medals, two American speed records, and a national championship. And "the next Bonnie Blair" doesn't plan on slowing down any time soon. "My goal is to have my own show on FitTV, teaching a kick-butt circuit-training routine," she says. "I love inspiring people to be their fittset."

HOW SHE STAYS MOTIVATED "Surpassing my achievements feels incredible; I want to replicate that again and again."

FUEL-UP ADVICE "I always split my desserts with a friend. You get all the taste you're craving, but only half the calories."

HOW SHE WINDS DOWN "If I'm stressed or frustrated, I take a yoga class or write in my journal-both help me to forget about a bad workout and leave me ready to try again."
