There's only so much weight someone can put on before it becomes a hinderance as bodybuilders often don't make good fighters and are too bulky. Usyk obviously isn't a true heavyweight and I think he would struggle to get much bigger than he is right now but he should just do what he did against AJ and try outbox him and dodge whatever Fury throws at him. Easier said than done though and I think Fury is a better boxer than AJ.
Indeed Usyk is not a heavyweight. Joshua weight was 8kg more than Oleksanders. And Tyson Fury is (or was) 16kg heavier than Joshua.
Btw, comparing Fury and Joshua, Fury is more faster. I think this is due to Anthony being a heavyweight because he has pumped his muscles, which hinder more than help. While Fury has a lot of weight in his "life buoy ring". But frankly, Fury is to big for Usyk. Speed wont help him to avoid Fury's bombs.
Yeah, I agree that there is a limit specially for some athletes as far as weight goes. Usyk and his team played it very well, just enough to go to the heavyweight minimum, not lose Usyk speed and body and head movement. Enough to give them a win against Joshua, perfect strategy.
@icopress - Joshua is exercising his rematch clause, so the fight might happen first quarter of next year. Much better to keep this thread or rename it if the fight officially happens.
