Kim is barely old enough to drive, but few can shred the gnar like the 18-year-old from Long Beach. The youngest woman ever to win an Olympic snowboarding medal, Kim burst onto the scene in 2018 when she took home the gold in the halfpipe competition during the Pyeongchang Games. She took home Best Female Athlete honors at the ESPYs during the same year.

The 4-foot-8 Biles defies the laws of physics on a daily basis. From the time Biles began competing in 2011 at the age of 13, she has completely dominated her sport. Biles took home four gold medals during the 2016 Summer Olympics, and has already cemented herself as one of the most decorated gymnasts ever — and many believe the greatest gymnast of all-time.
