The WBA, WBO, and IBF World Heavyweight Champion is undergoing a punishing training schedule knowing that Joshua will be desperate to avenge his loss in September last year.
And fight fans will notice that Usyk who has previously fought, and enjoyed great success, as a cruiserweight has bulked up considerably and is looking like a formidable heavyweight.
Before his 2020 points win over Derek Chisora, he claimed his ideal weight would be 16st, but for that London bout he could only reach 15st 7lb.
When he convincingly beat AJ at Tottenham Hotspur Stadium, he had managed to hit 15st 11lb of pure muscle and retained his speed, while his rival was 17st.
He looks well in excess of his dream weight — which could mean Joshua is in for an even tougher night. Many experts have praised Usyk’s speed and boxing ability.

His new frame means he can make strides towards also matching Joshua physically while hopefully retaining his speed and movement.
Usyk is now tapering down, as his build up enters the final phase, however former light-welterweight world champion Amir Khan has visited his training camp and can confirm that the champion has been training three times a day in order to be in peak condition.
Usyk revealed to Khan he is training three times a day and wakes up at 4:45am to begin his first session at 5am. When Khan asked the former undisputed cruiserweight champion if he was ready, he retorted: “I was born ready.”
After his win over Chisora, Usyk said: “I feel more powerful since moving up from cruiserweight. When it comes to boxing, me and my team will decide on the optimum weight for me to fight at.
“I will stay at that weight and it will be ideal for my movement — because that is my main skill.”
The Sun reveal that when Usyk visited London for the launch press conference for the Joshua fight, he met Chisora at a Russian spa. And Chisora, 38, revealed Usyk’s mind-blowing regime.
He said: “I told him he looked tired. He told me he had just finished swimming for five hours.
“I told him he was lying; he couldn’t swim for five hours.
“But his trainer told me it was true and then showed me a video of him in this huge Olympic pool just going up and down for five hours.”
Usyk has also been further developing his balance and speed. One routine revealed by talkSPORT involves standing on an exercise ball, while juggling tennis balls.
Joshua is also in hard training and has been urged by many experts such as Mike Tyson and David Haye to impose himself physically and not to risk being outboxed.
However, with Uysk’s new physique after his intense build up this may be easier said than done.
