Why are you se certain? Usyk had been a pudgy cruiser forever, but gained 20 lbs of pure muscle in an instant, past the age of 30, while cutting body fat. Those results don't happen without assistance; even Holyfield didn't change that quickly.
A diet won't help you gain 20lbs of shredded muscle. That is absurd, particularly for a 30 year-old athlete that had already been performing on a world class level. He wasn't in the gym and eating properly while he was dominating at cruiser? What a joke.
The most obvious 'roid use recently by the way is Wilder. He lost nearly 25lbs between his last 2 fights without having a belly. All within a year too. He's not even trying to hide it.
I should add some context here because why not. The picture comparison is Usyk 2013 weigh in against Joyce AT HW. 211 pounds. Second picture is Usyk in 2023 now fights at 220 pounds. So 10/15 pounds of muscle given he looks 225 there. Decent amount of mass for a boxer...he isn't bodybuilding and he isn't going around lifting massive weights with them dodgy joints. Make of it what you will. I don't think the extra mass does anything for him anyway...I think Fury will make him look like a blown up cruiserweight.
Yeah 210 out of training and came in 240 for Fury 3 and fatman 3 week camp Fury still manhandled him. Fury is a titan. A mental giant.
Rumour has it that Fury has tiny balls. In fact some have described that ol wedding tackle as looking like a fly with a big nose.
Difference between the two pics is a couple of weights sessions and better lighting after a few weeks of not training I can look slack and pudgy then hit the gym for a few sessions and I look solid again. Can only imagine that’s amplified for a top level athlete
If you look at the nipple indents that is a giveaway of mammory removal surgery which indicates overgrown mammory tissue or gynocomastia usually resultant from hormone manipulation. Tyson Fury and The Rock (WWE) among multitudes of others have these same nipple indents viewable in the photo on the right of Usyk indicating the same procedure. Developing gynocomastia in adulthood without external hormonal influence is extremely rare. Ultimately I have no opinion on the subject.
A lot of fighters look that way when they chub back up after a few months of their fight being over & aren't training any more it's pretty normal actually, Then once they start camp they get into shape & muscle memory kicks in along with SC, all the same, Wilder's transformation for the third Fury fight was something else as he must have very good genetics because if that was anyone else then there would be all sorts of allegations being made towards them, even Hollyfield who people think was on PED's didn't look that good.
You are not a world class boxer actively training for championship fights. Your comparison between Aleksander Usyk and yourself is invalid.
