37. Lolo Jones / HURDLER AND BOBSLEDDER
At 33-years-old, Jones now trains for two Olympic sports—hurdling and bobsledding. She has battled some injuries over the course of her career, but fitness is a huge part of her lifestyle: Jones endorses Orangetheory Fitness, an interval workout that combines the treadmill, rowing machine, TRX training and free-weights, and also does yoga and track workouts.
