Mikaela Shiffrin relies on powerful legs and stability to excel in her sport, and it only makes sense that she’d hone them to perfection. The 27-year-old alpine skier, who has two Olympic gold medals under her belt, is so serious about her training that she actually has a Google doc where she tracks the results of each workout session, according to SI.
Using a scale of one to 10, one being “rested” and 10 “close to passing out,” Shiffrin documents how she feels after each training run – and it’s almost always close to 10.
