Simone Biles is one of the top US athletes, winning gold at the 2016 Olympics and becoming the first American gymnast -- and tenth in history -- to win a medal in every event.

The 22-year-old gymnast continues to make history in her sport, and aside from winning her sixth national all-around title, Biles landed a never-before-seen triple-double on Sunday.

The US Gymnastics Championships in Kansas City this weekend was the perfect stage for Biles to continue writing history, as she became the first woman ever to land a triple-double (two backflips and three twists) while competing during her floor routine.

More records

The Kansas Nationals competitions saw Biles make more history as she also became the first gymnast to attempt and land a double-double (two twists and two somersaults), dismounting from a high beam.

Biles most focus onto the 2020 Tokyo Olympics, which she said would be her last, but for now, she will enjoy celebrating her sixth national all-around title with a score of 118.500. The last woman to win six US all-around gold medals was Clara Schroth-Lomady between 1945 and 1952.
