Simone Biles trained in a secret gym to regain her form

Simone Biles publicly thanked the Japanese gym where she secretly trained after withdrawing from multiple gymnastics events at the Tokyo Olympics, citing her mental health.

In a tweet on Wednesday, Biles expressed her gratitude to Juntendo University “for allowing me to come train separately to try to get my skills back.”

Biles’ message confirmed a report by The Wall Street Journal that the American gymnast had been privately training to regain her air awareness. The Juntendo University gym allowed Biles to overcome the “twisties” for hours at a time away from the glare of the Games.

Biles leaves Tokyo with a bronze medal on balance beam and a silver from team competition, for a total of seven medals across two Olympics.
