Hafthór Björnsson is finished filming for the sixth season of Game of Thrones (in which he plays “The Mountain”). The new series is currently airing on HBO, so he’s now spending the bulk of his time training for the upcoming 2016 World’s Strongest Man Competition. Because this is no ordinary contest and involves giant men and women lifting absurdly heavy things, the training required is anything but ordinary.

That’s how we get this insane video of Björnsson pulling a semi truck down the road in pouring rain as effortlessly as most of us would pull a 100-pound weighted sled. Björnsson pulls the truck, which probably weighs more than 20,000 pounds, with ease, leaving us dumbfounded. This surely makes Björnsson one of the favorites to win at the World’s Strongest Man competition.

We also like how he included in his caption the hashtag #NoExcuses, as if the rain were the real challenge he was facing, not pulling an enormous eighteen-wheeler. “The Mountain” is crazy—and crazy strong.
