If you look up "fierce" in the dictionary, you're likely to find the U.S. women’s gymnastics team. Same goes for five-peat.
Despite some setbacks -- like 16-year-old Sunisa Lee’s fall off the balance beam and 16-year-old Grace McCallum’s pirouette error on the uneven bars -- Team USA was led to gold by 22-year-old Simone Biles.
The four-time Olympic gold medalist proved to still be unstoppable with her athleticism and incredible skill.
Over the weekend, Biles stuck not one but two signature jaw-dropping moves: the double-double dismount on the balance beam and triple-double on the floor.
Both are performances that people are still buzzing about and that the International Gymnast Federation even found controversial for the added safety risk.
Nevertheless, the now most-decorated female gymnast in history will have one of the two moves named after her. She holds an astounding 15 world championship gold medals, and 21 world championship medals total.
The fifth consecutive world championship win ties a record set by Romania from 1994 to 2001.
Biles will defend her women’s individual all-around title on Thursday.
And the Tokyo Olympics are now just 10 months away.
