So, apparently, Game of Thrones’ the Mountain (AKA Hafþór Júlíus Björnsson) has not always been an absolute behemoth. Quite the contrary, actually.

At least through age 20, the 6’ 8” Icelander was a top-level basketball player. You can check out a brief profile of him here. According to this bodybuilding forum, Bjornsson started out at 240 pounds when he discovered strongman competitions while rehabbing from injuries he suffered during his basketball career.

His peak weight? 440 pounds. These days, he is 26 years old and hovers around 400.

So, um, that happens totally naturally, right? I mean, it has to be pretty easy to put on 200 pounds if you set your mind to it.
