British-Nigerian boxer, Anthony Joshua is set to spend four days alone in a pitch black room as part of an experience he paid for.
He was said to have paid £2,000 for the surreal experience which is a style of retreat used by various sporting stars.
It was gathered that the isolation game serves as a method of meditation to help athletes be alone with their thoughts.
Joshua took to his Instagram page and announced that he was embarking on the retreat with a friend, but they will be in different rooms.
Sharing photos, the former WBA champion wrote: “Myself and [my friend] are about to embrace the darkness and solitude for four days (separate rooms).
“Isolated with nothing to do except relax and clear the mind while being immersed in infinite darkness.”
The 34-year-old has been fed via food passed into the room but there has been no social interaction or light all week. Anthony Joshua and his buddie will emerge on Friday.
NFL star Aaron Rodgers, who embarked on a similar retreat, shared his experience in March, stating:
“It was a great reset for me, for my body and my mind,’ the 39-year-old said of the four-day excursion. ‘Maybe a little bit longer than I needed. I feel like by the time I got to the fourth day, I was like, ”Alright, I’m ready to come out”.
