OLEKSANDR USYSK appears to have put on muscle while preparing for his fight against Anthony Joshua.
He will be fighting WBO, WBA, and IBF champion Joshua on Saturday night.
Usyk unified the cruiserweight division and decided to move up into the land the giants.
Some critics believe that the Ukrainian heavyweight champion will not be big enough.
However, Usyk's training photos show that he should not be afraid of the big night under 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.
BETTING SPECIAL - GET JOSHUA TO WIN IN ROUNDS 1-6 AT 60/1 OR ANYTIME AT 25/1"Not that Usyk isn't experienced in dealing with this, but just going by 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.
