The man behind “The Mountain” won the World’s Strongest Man competition in the Philippines, according to The New York Times. After a number of second and third place finishes over the years, Björnsson, 29, took home his first title win on Sunday. The competition is set to air in the U.S. on CBS beginning in June. NOEL CELIS/AFP/Getty Images The Icelandic actor’s fight to the finish involved two days of strength tests, which included pulling a truck, races while hauling anvils and other heavy objects, and, of course, overhead deadlifts. Björnsson, who stands at 6-foot-9 and weighs in around 400 lbs., posted on Instagram following the bout.

Also want to thank my sponsors, @kjotkompani @sbdapparel @roguefitness. Congratulations to @kieliszkowskimateusz and @shawstrength for their second and third finishes!” Björnsson also holds the world record for deadlifting 1,041 lbs. a few months ago. Staying his size is harder than it looks, Björnsson told Men’s Fitness recently. “I need to force feed myself,” he said, describing his diet, which begins each day with “six eggs, bacon and oatmeal, followed two hours later by some sliced steak and rice.” “It’s a full-time job to be this size,” he added. HBO The final season of Game of Thrones airs on HBO in 2019.
