The 22-year-old threw an unbelievable triple-twisting combination with a double flip (triple-double) before successfully landing it on a gymnastics mat, which is allowed at the national championships.

Biles’ insane routine earned praise and admiration from gymnastics lovers who said the newly devised floor routine was “humanly impossible.”

“No kidding – she gets 8 feet in the air from the ground? If I hadn’t seen it I would not believe it’s humanly possible. Incredible,” one user wrote.

“Anti gravity belts are banned in gymnastics, aren’t they?” another person added.

“How is that possible? She jumped like 3x her height!” another comment read.

Earlier, the unstoppable US athlete demonstrated a new double-somersault dismount from the balance beam, establishing herself as the one and only favorite to win practically all medals in women’s gymnastics at the 2020 Olympics in Tokyo.

Biles won her sixth US national title during a two-day, all-around event, posting the sum of 118.500 points, nearly five points ahead of silver medalist Sunisa Lee, and almost eight points ahead of Grace McCallum, who finished third.
