Anthony Joshua looked happier as he enjoyed a night out with friends in the capital—after revealing the strict rules of the gym ahead of entering training camp for his rematch with Daniel Dubois. He recently shared the strict training camp rules as he prepares for the critical rematch with Daniel Dubois.

But Anthony Joshua made the most of his free time on Saturday night as he spent the evening with friends in London.

Downtime: Anthony Joshua looked chipper as he enjoyed a night out with pals in Mayfair on Saturday.

The cheerful 34-year-old professional boxer flashed a big smile after enjoying a night out at Inca, Mayfair—a restaurant and live performance bar where visitors are taken on a sensory journey through South America.

The unified world heavyweight champion looked sharp in an all-black outfit—shirt, jeans, and sneakers. His Saturday night look was completed with a leather jacket, and a bit of chain could be seen peeking out from his shirt. The Watford-born athlete and his friends put on a lively show as they shared jokes in front of the cameras.

Earlier this week, Anthony shared the strict rules of his training camp as he prepares for the crucial rematch with Daniel Dubois, warning any “spies” in his gym to “get lost.”

The boxer is shaking up his usual surroundings as he fights to reclaim the world title—ready to work with a new trainer and move away from his Sheffield base—and he has shared a new set of gym rules that he and his training partners will follow for the upcoming camp.

He issued the challenge with a notice displaying 10 rules, posted on his Instagram Story, which included a warning that “no fooling around” is allowed in his gym, telling guests that “boxing is serious business.”

And in another stern reminder of the importance of the upcoming fight, he told any “spies and traitors” who might enter his gym to “get lost because we don’t want you.”

Visitors were also asked to “keep quiet until you know what you’re talking about” and urged to “arrive on time” for training and sessions, and to “give 100 percent” because “we will too.”

The heavyweight star has yet to officially sign a deal to face Daniel Dubois again after a bruising night in September.

Joshua’s clear and direct messages come after he said in October that he’s “tired of losing” and vowed to give Dubois a “fight” in the upcoming rematch, saying he’s “frustrated” about losing the title and that “there may be a knockdown” when they meet in the ring again.
