Simone Biles shatters record for most medals won at world gymnastics championships

With her two wins on Sunday, Simone Biles became the most decorated gymnast in world championship history.

Biles took home two gold medals — one for the balance beam and the other for her floor exercise — and now has 25 World Championship medals. Earlier in the competition, she won gold in the team competition, all-around and vault; she came in fifth on the uneven bars. The 22-year-old's Sunday wins put her ahead of Vitaly Scherbo, who earned the previous record of 23 world medals during the 1990s.

Biles' floor performance was so outstanding, with a triple-twisting double back, she earned a score of 15.133, one point higher than the second-place finisher, U.S. gymnast Sunisa Lee.
