Strongman and actor Hafthor Bjornsson -- aka "The Mountain" from 'Game of Thrones' -- picked up a barbell weighing 1,042 FREAKIN' POUNDS ... and it's straight-up ridiculous!!
Thor -- who's 6'9" and 400-ish lbs. -- is a legendary strongman. He won the World's Strongest Man, Europe's Strongest Man and Arnold Strongman Classic ... all in 2018.
So, he's literally the strongest person in the world (4x WSM winner Brian Shaw and '17 WSM champ Eddie Hall might disagree).
The lift went down earlier this week at Bjornsson's gym in his home country of Iceland .
