This is a video of Hafþór "Thor" Björnsson, the actual human giant and real-life viking marauder who plays "The Mountain" on Game Of Thrones, at a dead-lifting competition.
And those are six massive tires weighing a combined total of 994 pounds that he's lifting up.
Here he is doing a similar to thing a car.
And here he is doing the same thing to some big wooden thing.
Also, here's a scary fact for you, in 2014 Björnsson came in second in the " World's Strongest Man" competition. Which means, that as frightening as this guy is, there's someone out there even more frightening.
