Being called "Iceland's Strongest Man" is no small feat. But it is a title that Hafthor Julius Bjornsson, better known to "Game of Thrones" fans as "The Mountain," knows all too well. That's because he has been named the strongest man in Iceland — for the fifth year in a row.

That might not be that significant in America, but in Iceland, it is the stuff of Nordic legend. Icelandic men are, quite simply, giants. And these über-strong men are national icons because of their resemblance to Vikings. But Björnsson is a legitimate legend, as shown by this video:

The log he is carrying is no ordinary log. It was the mast of the Ormen Lange, one of the most famous of the Viking longships. It weighs 640 kg (1,410 lbs). Though he only carried it for five steps, no one man has been able to carry it since the days of real Vikings until Björnsson did it in February, which basically makes him a modern-day Viking.
