American superstar Simone Biles continues to break new ground in gymnastics, completing a Yurchenko double pike during the US Classic at Indianapolis.
With several manoeuvres already named after her, the 24-year-old has become the first woman to attempt - and complete - the difficult vault, as she prepares to defend four Olympic titles at Tokyo in July-August.
The Yurchenko - named after former Soviet gymnast Natalia Yurchenko - refers to a vault that begins with a round-off onto the springboard and a back handspring onto the horse.
The move was first performed by Russian Viktor Levinkov, but it was banned by the national men's programme, before Yurchenko adopted and perfected it.
Biles has added her unique twist with a double rotation in mid-air, which she has worked to perfect for several months.
"It's very, very challenging," coach Laurent Landi told 60 Minutes in February. "And what's scary is that people can get hurt.
"You do a short landing, you can hurt your ankles. It's a dangerous vault."
Biles became a household name at the 2016 Rio Olympics, where she captured all-around, vault and floor gold medals, and led the United States to team glory.
After her latest exploits, social media exploded...
Biles last competed at the 2019 world championships, but during her comeback, she wore a rhinestone goat on the back of her leoptard.
"It was really nerve-racking, but I'm just happy to be back out there," she has told NBC Sports.
Biles won the all-around competition at Indianapolis, despite falling off the uneven bars.
Over the past eight years, she has also won 19 world titles, including five all-around crowns, and has been named Laureus World Sportswoman of the Year three times, including back-to-back in 2019-20.
In February, she called out ESPN's Sportscenter for not including women in its 'Greatest of All Time' poster.
