As he gets ready for a pivotal rematch with Oleksandr Usyk, he recently revealed his stringent training camp guidelines.

However, Anthony Joshua spent Saturday night with friends in London, making the most of his vacation.

After spending an evening at Inca, Mayfair, a show restaurant and bar that takes patrons on a sensory adventure through South America, the gregarious 32-year-old professional boxer was beaming. A leather jacket completed his Saturday night ensemble, and a small piece of chain was visible showing through the shirt.

In front of the cameras, the Watford-born athlete and his pals shared a laugh while putting on an enthusiastic show.

Anthony warned any’spies’ in his gym to off’ earlier this week as he revealed his stringent training camp guidelines in front of a pivotal showdown with Oleksandr Usyk.

As he attempts to regain his world titles, the boxer is prepared to move from his base in Sheffield and work under a new trainer. He has also revealed a new set of gym regulations that he and his sparring partners would follow during the next camp.

On his Instagram Story, he issued a note outlining ten regulations, warning that there can be “no  about” in his gym and informing guests that “boxing is a serious business.”Additionally, visitors are advised to “be on time” for sparring and lessons, “give 100 per cent” since “we will too,” and to “shut your mouth until you know what you’re talking about.”

After giving up his three world title belts in a unanimous points loss at the Tottenham Hotspur Stadium in September, the heavyweight star has not yet formally signed on to fight the Ukrainian again.

However, he is speeding up his preparations for what is considered to be the greatest bout of his career to date, which is anticipated to take place in the spring at Cardiff’s Principality Stadium.

Joshua’s succinct and straightforward remarks follow his declaration in October that he was “tired of losing” and that he was “annoyed” over losing his titles. He also stated that the Ukrainian “may get thrown on the floor” if they fight again.
