ANTHONY JOSHUA is putting in the hard yards in the gym just four days after knocking out Francis Ngannou in Saudi Arabia.

The British star wants a speedy return to the ring after his stunning victory and is wasting no time preparing for it.

Joshua posted photos on Instagram showing him hitting an early morning workout with his strength & conditioning team in a Dubai gym.

The heavyweight performs lunges and flexes his physique at the end of the session.

While the 34-year-old has his eyes set on a fight with British champion Tyson Fury, Joshua will likely have to wait at least a year to get his hands on the “Gypsy King”.

Fury is contracted to an immediate rematch with Oleksandr Usyk after their bout scheduled for May 18.

Former UFC champion Ngannou only lasted two rounds with Joshua as he was dropped three times before the fight was waved off by the referee Richard Gonzalez.

Following his recent hot streak of wins in the ring, the former Olympic champion mentioned three names who he has in mind to take on, in between his wait to challenge Fury.

When questioned on who he wants to fight next he said: “Wilder, Zhang, Parker. All of them.”

Joshua had originally signed to face Deontay Wilder until the American fell to a shock defeat by Joseph Parker.

Parker then beat Zhilei Zhang in his next fight and is now a possible option for AJ.

The two fought in 2018, with Joshua securing the victory on points.

Fury has been given the green light by the WBC to fight Joshua if he defeats Usyk.

Mauricio Sulaiman – president of the WBC, in which Fury is champion – would give the go-ahead to face AJ after Usyk.

Sulaiman told Sky Sports: “The WBC was presented a sanction request which was to fight for the undisputed.

“The WBC accepted that sanctioning and we accepted the rematch they have requested.

“But, if it is not anything to do with contractual or promotion, we would absolutely accept the winner to fight Joshua.

“The WBC has been very much attentive to this matter. So we have completely freed the ground for the undisputed, for a rematch, and for another fight of that level.

“The WBC position right now is very open to support the undisputed champion taking on the fights that the fans want to see.”
