He went from 175lbs at 20 years old in 2001, to 236lbs at 23 years old in 2003. He gained 61lbs in 3 years. He is clearly a cruiser weight fighter at best.
He has small wrists. Looks like a small bone structure overall. I say CW comfortably but would all depend if he can lose any weight from that massive head of his.
Big cruiser/kinda small heavy. He clearly filled in (not a fat joke, just a 'getting broader/thicker as you get older thing') since then. Of course, then he DID get fat.
He surely isn't a heavyweight, he's billed as being 6'4" for some reason when he's 6'1", he's also grossly overweight, you can tell just by looking at him, he's not like when Chisora was 275lb, he was chubby but there was still muscle there underneath, Areolla is a skinny guy covered in fat, not a big guy covered in fat, he has no shoulder muscles, no arm muscles, nothing, just 40+ lbs of excess fat
he looked very odd at that weight, i will try and find the pic i had at 165 pound...he even had some muscle defination if i remember correctly
