When you think of Gregor 'The Mountain' Clegane from 'Game Of Thrones', there's probably one thing that comes to mind - his size.
Hafthór Júlíus Björnsson is the actor who plays Clegane in the HBO series - and to say he's built is an understatement.
Now, the 6’9” actor has opened up about his intense diet and fitness regime which has seen him bulk up from 230lbs (16 stone 4lbs) to 396lbs (28 stone 2lbs) in seven years.
He's now that strong he can pull a 15-ton plane.
Speaking to GQ, the Icelandic actor said that he has developed his huge frame by training well, sleeping well and eating well.
Björnsson said that the main reason he has gotten bigger over the years is that he doesn't do much cardio exercise anymore and, instead, he just eats more.
In total, Björnsson eats between six and eight meals every day - that's more than double the meals the average person consumes.
"It’s just like constantly work for me: I have to eat every two hours to maintain my body mass. It is not easy. When I’m filming, I always have to have breaks to eat," he explained.
His staple diet consists of sweet potatoes and "a lot" of meat (mainly chicken) and fish. He's also a huge fan of cocoa butter, almonds and greens such as spinach, avocado and broccoli.
"I eat very healthy overall - but because of my weight, I need fast carbs, easy carbs. So maybe before a training session or after a training session, I eat what I want," he said.
The training sessions themselves consist of weightlighting and, you guessed it, weightlifting.
Björnsson can deadlift 990lbs and, when he's not doing that, he's pulling trucks and planes which weigh anywhere between 10 and 15 tons.
We're in awe.
