Simone competed a triple-twisting double on floor (that's two flips and three twists in a tuck position) for the first time at the 2019 US Gymnastics Championships. She fell on the skill during night one but landed it on night two, making her the first woman to land that skill in competition. After landing this J-level skill during the qualification round of 2019 Worlds, it will now be dubbed the Biles II. Watch her full routine from that night here (the Biles II is the first tumbling pass here).
