How did this famous 'Game of Thrones' actor lose 120 pounds?

Do you remember Gregor 'The Mountain' Clegane from 'Game of Thrones'? Well, the actor has changed. In fact, you need to imagine the man in the image above with 120 pounds less.

Hafþór Júlíus Björnsson, known as 'The Mountain', has experienced a full-on physical change. He now has a slimmer body, although you can see he is still as intimidating as ever.

It seems like a decade has passed since the final episode of 'Game of Thrones', but it was actually released in May 2019. Since then, the actors of the legendary show have transformed, but Hafþór Júlíus Björnsson has experienced a most radical change.

Born in 1988, Hafþór Júlíus Björnsson is 6'9 tall. During his time in 'Game of Thrones', the Icelandic actor reached 440 pounds of weight.

Hafþór Júlíus Björnsson was titled the strongest man in the world when he surpassed the world record for Elephant Bar deadlift with 1044 pounds. No wonder his nickname is 'The Mountain.'

His workout routine is unthinkable for 99,9% of the population. It helped him become the strongest man in the world.

Once he accomplished that goal, 'The Mountain' found another challenge: boxing.

To prepare as a boxer, Hafþór Júlíus Björnsson followed a strict training regime and a high protein diet that put him in his actual weight: 321 pounds.

Participating in the titan weight category, 'The Mountain' won against the professional fighters Devon Larrat (in the first round) and Eddie Hall. The latter match was considered 'The Heaviest Match in Boxing History.'

Thanks to his absolute dedication to training, Hafþór Júlíus Björnsson may become a legendary boxing star.

In fact, according to the actor on his social media, he trained harder than ever before to reach his current weight. It was harder than when he had 440 pounds of pure muscle.

Since the end of 'Game of Thrones', it seems like his acting career has taken a back seat. Still, we think his appearance is perfect for the current movie industry in which Marvel superheroes and big guys dominate.

We were able to see 'The Mountain' in film projects like 'Pharaoh's War' (2019) starring Mike Tyson. There, Hafþór Júlíus Björnsson played the role of Frank.

More recently, Hafþór Júlíus Björnsson appeared in Robert Eggers' new movie 'The Northman' (2022) starring Nicole Kidman, Alexander Skarsgård, Anya Taylor-Joy, and Willem Dafoe. There, he got to demonstrate once more his incredible physical strength.

By now, 'The Mountain' is in a position where he can pursue his acting career in Hollywood or consolidate his new boxing career.

Whatever the future might hold for him, we will always remember Hafþór Júlíus Björnsson (Gregor Clegane) for his epic fight scene with Pedro Pascal (Oberyn Martell). Undoubtedly, it was one of the most memorable moments of 'Game of Thrones'.
