Olympian Simone Biles became the first woman in nearly 70 years to win a sixth US senior all-around gymnastics titles - and she marked the occasion by also becoming the first woman to land a triple-twisting, double back maneuver during her floor routine. 

On Friday, Biles made history by becoming the first gymnast ever to land a double twisting, double somersault dismount off the balance beam. 

The four-time gold medalist and 2020 Tokyo Olympics favorite finished the final night of the US women's gymnastics championships with a score of 118.500 to beat Sunisa Lee (113.550) and Grace McCallum (111.850).  

Given that comfortable entering Sunday, the 22-year-old Biles could have taken the maneuver dubbed 'the triple-double' out of her routine on Sunday. By many accounts, she already had another national title in hand by that point of the program, matching Clara Schroth Lomady, who won her sixth US crown in 1952. 

Biles's coach Laurent Landi left the option up to her after the Olympic champion's bid to become the first woman to complete the triple-double in competition came up a bit short on Friday.
