In her first year of dental school, Audrey Weber, 27, has less time for ski-specific training and instead shifted her focus to the gym, where she's found success with CrossFit. "Currently, I am 13 months into my own personal case study called, 'How Fit Can an Ex-Cross Country Ski Racer Stay on Four Hours of Training Per Week?' " she says. "Some preliminary results are in, and the findings are quite interesting." she says.
