Here's James Harrison proving he's STILL hands down the most superhuman person ever associated with the NFL ... bench pressing a stunning 525 POUNDS!!!
The Pittsburgh Steelers legend posted the footage of the gym feat on Tuesday ... and it's absolutely insane.
Check out the clip, Harrison needs several seconds to pump himself up for the lift -- and then he attacks the weights ... and watch how the plates make the bar bend!!!
42-year-old Harrison screamed during the entire lift -- "GET OFF ME!!!" -- and the whole thing was intense as hell!
