OLEKSANDRUSYK appears to have put on muscle while preparing for his fight against Anthony Joshua for the world title.
He will be fighting WBO, WBA, and IBF champion Joshua on September 25, his third heavyweight fight.
Usyk unified the cruiserweight division and decided to move up into the land the giants.
Some critics believe that the Ukrainian team will be too small to become a world champion.
However, judging from his recent training photos, Usyk shouldn't be afraid of his big night at the Tottenham Stadium lights.
Fabio Wardley, a rising Brit heavyweight, said that despite his undefeated record in boxing, it will be too difficult to face AJ.
Betfred TV's Boxing Show interviewed him: "[Oleksandr Uzyk] has not put together the best performances since his time in the heavyweight division.
"So, to jump in with Joshua, it's quite the leap.
"I don't mean that Usyk isn't experienced in dealing with this, but based on what we've seen, that's where I'd edge it.
"I believe he found it slightly more difficult to adjust into heavyweight than he originally anticipated."
The 34-year-old Usyk has gained considerable mass to challenge Joshua and stop the Brits' eagerly-awaited showdown with Tyson Fury.
Eddie Hearn, however, believes that the undefeated Ukrainian heavyweight is still too big.
TalkSPORT was informed by him that Usyk would never be considered a full-fledged heavyweight. He is a big, muscular heavyweight.
However, the Matchroom Boxing chief believes that Olympic gold medallist Usyk makes up his short stature with his wide range of skills.
He said, "What he will always possess is a tremendous amount of skill."

"It takes time to get into heavyweight. So let's put it this way: It would have been a lot easier fight for AJ a whole year and a half ago.
"Now that Usyk has fought in a real heavyweight contest in Chisora it will help him to begin to understand what is needed.
But AJ is a different type of beast. We'll see. A big man will always beat a small one.
