Believe it or not, Mastro's favorite workout doesn't involve a snowboard — or even snow, for that matter. "My favorite workout is cross training," she told NBC Olympics. "I love doing different sports, getting outside, and still being able to get a workout."
Mastro played competitive soccer until the age of 16, when she had to decide between pursuing soccer or snowboarding full time. While she chose the latter, she credits soccer for teaching her how to think fast on her feet, and it's one of the many sports that make up her cross-training regimen today. She also surfs, plays tennis, wakesurfs, and has recently gotten into mountain biking.
