39. Mattie Rogers / WEIGHTLIFTING
The weightlifter from Apopka, Fla., is already an internet viral video sensation after she dropped a bar which rolled into and broke a window. The 20-year-old got her start in CrossFit and just barely missed out on making the U.S. team for Rio, but she has already broken eight records (two for the snatch, three for the clean-and-jerk, and three overall records) and is poised to be a weightlifting star.
