I have read everything written about Paul, and from the credible historians, none can verify a bench press, though I have no doubt it would be massive.
For the record, I think Paul is the Strongest man to have ever lived, but most of his lifts cant be verified, which is a shame. If he reckons he benched around 640lbs, with wheels etc, I believe him, but it cant be recorded in History, because now we have the internet, and everybodys cousin does that
Look up Ken Patera, he was immensely strong overhead. I have his best lifts in a Milo, I really cant be fucked looking for it though.
I know he jerked 500lb , first yank, he also pressed it
