Simone Biles might be the best female gymnast ever. At 22 years, she already has five Olympic medals, and she has broken several records. There are even moves named after her.
Recently, Simone broke a record by performing the first triple double as a female in gymnastics history. She has won four individual gold medals in Rio in 2016, and a medal in group categories.
Simone won the all-around, vault, and floor gold medal, and bronze for the balance-beam. She was also part of the gold-medal winning team dubbed the Final Five.
