Stunning slow-motion video of Simone Biles' most impressive stunt on the floor shows her mind-boggling athleticism

• Simone Biles won her record seventh national all-around title at the US Gymnastics Championships.
• Her floor routines earned a 29.600 cumulative score - a full point higher than the next-best score.
• A slow-motion video of Biles' most daring stunt on the floor shows just how wild her athleticism is.

Simone Biles on Sunday won another all-around title, because of course she did.

Propelled by first-place finishes in the vault, beam, and floor events, the 24-year-old gymnastics GOAT cruised to her record seventh national all-around title at the US Gymnastics Championships. Biles beat the next-best finisher - Olympic hopeful Sunisa Lee - by an incredible 4.7-point margin to remain undefeated at the event.

Though Biles' unparalleled athleticism powered her throughout all of the competition's events, her dominance was most apparent on the floor. Her two floor exercises earned a 29.600 cumulative score - one and a half points higher than the second-place gymnast.

The Houston native is known for regularly performing stunts that other athletes simply cannot pull off, and her floor routine on Friday - during the first leg of the event - was no exception. She performed two skills so impressive and unprecedented that they're both named for Biles herself.

On the first pass, the four-time Olympic gold medalist stunned with the Biles II - a triple-twisting double back tuck.

A slow-motion video of the skill shows just how incredible and breathtaking Biles' feats of athleticism truly are. Check out the extraordinary clip shared by Timothy Burke below:

The rest of Biles' exercise shined, too. She stayed in bounds on all but one tumbling pass, and the routine's 6.8 difficulty score - or D-score - was tied for the highest performed by any gymnast throughout the four events at the meet, according to ABC13.

It's safe to assume Biles will ride this momentum into US Olympic Team Trials in St. Louis later this month, though the event is practically a formality for the most dominant athlete on the planet. She's all but certainly secured a spot on Team USA's four-person squad headed to Tokyo in July - but who will fill the other three spots remains to be seen.
