I heard Povetkin bench pressed 360 lbs when he was on PEDs, now that he wasn't allowed to take them his bench press dropped significantly. As well as stamina and punching power. That PED Povetkin who fought Duhaupas could have KO'ed Juiceshua.
He's probably still benefiting from years of doping even after stopping. https://www.bbc.co.uk/news/science-environment-24730151
Dillian Whyte is another one who has a very high bench press. I reckon Bellew and Wilder are probably the only heavyweights not on gear based on how extremely critical they are of the likes of Ortiz and Povetkin. Based on their physiques it's possibly true. I never hear any complaints from Joshua (a possible sign of guilt?).
Or it could be a case of accuse and put down everybody else so as nobody looks at you....... I suspect Bellew will be on that pharmaceutical grade gear signed off by the Matchroom doctor for the Usyk fight.
