Ser Gregor Clegane or The Mountain, played by Hafþór Júlíus Björnsson (how do you pronounce that?) is easily one of the most fearsome characters on Game Of Thrones. “”I’d be a bloody fool if he didn’t frighten me. He’s freakish big and freakish strong. And quicker than you’d expect for a man of that size,” said Bronn, another character from the show.

It’s not just the character that is portrayed like that, The Mountain is freakish big and freakish strong in real life too. He has made the top three in The World’s Strongest Man competition, for three consecutive years.

So to analyse what makes him what he is, we take a close look at his fitness and diet regime.

According to the World’s Strongest Man website, The Mountain can squat 250 kg, bench press 230 kg and deadlift 420 kg. The 6’ 9’’ doesn’t swear by a specific fitness routine, and adapts his workouts based on whether he needs to build endurance or build strength. “When people ask me about my routine, it’s hard to say because I change it every week. If you always train the same way your body gets used to it and you stop seeing results after a few weeks,” The Mountain was quoted as saying by Men’s Health.

That said, a fair portion of his workouts focus on old-school exercises like squats, bench press and deadlifts – all done with an insane amount of weight for 3-5 reps.

So what does the man eat to provide fuel for so much exercise?

In a Facebook post, The Mountain shared his diet which seems enough to feed a village.
