Having won a combined total of nineteen Olympic and World Championship medals, Biles is the most decorated American gymnast. She took this over from Shannon Miller, who had held this record since 1996. With her win in Rio, Biles became the sixth woman to have won an individual all-around title at both the World Championships and the Olympic Games. With four Olympic gold medals, Biles set a new American record for most gold medals in women’s gymnastics at a single game.
