Competing at the 2019 World Championships in Stuttgart, Germany over the weekend, the 22-year-old successfully landed a triple-double – a windy move involving a double backflip and three twists – during her floor routine. USA Gymnastics later tweeted that the unprecedented move would be officially dubbed the “Biles II”. 

This came shortly after she did an unprecedented double-double dismount – a backflip with two twists – on the balance beam, to also be named the “Biles”. 

Biles became the first woman in almost 70 years to win a sixth all-around title at the US Gymnastics Championships in August. But she wasn’t just there to match records, she was there to break them: the four-time Olympic gold medalist took on the triple-twisting-double somersault, a move so challenging that no other female gymnast has ever attempted it in a competition. One so difficult that even Biles’ coach left the decision in the hands of his pupil. To give you a better idea of the feat, one Twitter user pointed out that at the peak of her floor routine, Biles was 10 feet off the mat – two feet higher than the high jump world record.

And she wasn’t done – at the same competition, she also took on an unprecedented move on the balance beam: a double-twisting, double somersault dismount. A move so difficult that no other woman has ever tried it on the balance beam in a competition. And of course – she landed it.

At a qualifying competition for the World Championships in 2018, Biles stunned onlookers when she performed a brand-new vault that has only ever been successfully performed by men. The original version, called the “Cheng” after Chinese gymnast Cheng Fei, is considered one of the most difficult vaults in gymnastics. Not only did Biles do it, but she upped the ante by adding in an extra half-twist, turning the sequence – a round-off, half on, front double full off – into an entirely new, and unprecedented, move.

Biles made history at the 2018 World Championships in Doha last year, when she landed six medals – four of them gold – making her the most decorated female gymnast in the history of the world championships. A remarkable feat in itself, made even more inspiring by the fact she was hospitalised the night before the competition in an emergency room with a kidney stone – which she affectionately nicknamed “The Doha Pearl” – and was forced to soldier through the pain due to doping regulations precluding prescription medication.

The floor has long been Biles’ favourite discipline, and we can tell by the smiles, techno music and the sorts of eye-watering flips most of us can only dream of. Her former coach Aimee Boorman told The Guardian that the floor is where Biles “just plays”. This is the same routine she performed at P&G Gymnastics Championships and then at the Rio Olympics, where she won gold.
