Winning a combined 30 Olympic and World Championship medals, Simone Biles is the most decorated American gymnast, full stop. And her story intersects with the two most famous and winning coaches of USA Gymnastics, Bela and Martha Karolyi. The Karolyis are the subject of a new 30 for 30 investigative podcast, "Heavy Medals: Inside the Karolyi Gymnastics Empire." It includes a look at their complicity in the rampant sexual abuse of athletes by medical director Larry Nassar, and how Biles navigated their restrictive culture and spoke out against abuse. ESPN's Alyssa Roenigk shares the story of how Biles found a way to win outside the norms of USA Gymnastics and the Karolyis.
