Simone Biles told New York Magazine she "should have quit" gymnastics before the Tokyo Olympics instead of participating in the Games.
Biles, 24, said that the reasons she withdrew from the team competition and four individual events went far beyond a case of the twisties.
The twisties refer to a feeling where gymnasts feel lost in the air, preventing athletes from completing skills at their normal ability.
During the Games, Biles dealt with her mental health and the unexpected death of her aunt. The gymnast, who is currently not training as she goes through therapy, says her recovery is still a "work in progress.
