Gregor "The Mountain" Clegane from Game of Thrones (his real name is Hafthor Julius Bjornsson) is literally the strongest man in Iceland. Measuring 6'9" and weighing a whopping 419-pounds, the actor has won the title for the past five years in a row. Watch him lift very heavy boulders and then lift very heavy balls and then rip his shirt off.

Iceland's Strongest Man 2015 - Atlas Stones First day was yesterday. I won all three events. 5 more to go today.
