The famous Game of Thrones character, Gregor Clegane or ‘The Mountain,’ portrayed by none other than Hafþór Júlíus Björnsson, has broken the deadlift world record. Gregor Clegane’s deadlift record of 510 kilograms (1,124 pounds) in the Strongman 2025 competition held in Birmingham has certainly made the Icelandic actor-turned-athlete more recognizable.
With this lift, The Mountain himself broke the deadlift world record he had previously set earlier this year at 505 kilograms (1,113 pounds).
[TRENDING] Details of the Record-Breaking Lift
If you have watched the American fantasy drama television series Game of Thrones, then you might be familiar with the famous character, Gregor Clegane, who is often called by the nickname, ‘The Mountain that Rides.’ The character was played by an Icelandic strongman, Hafþór Júlíus Björnsson, who has recently set a new strongman world record in 2025 by lifting a massive 510 kg (1,124 lbs) at the Mutant World Deadlift Championships in Birmingham.
Following Hafþór Júlíus Björnsson’s deadlift of 510 kg, he has surpassed his previous record of 505 kg, breaking the record for the third time. Despite the commoner observing the weight as massive during the event, Björnsson lifted the weight effortlessly, leaving his fans in awe. In response to the ongoing talk regarding how he deadlifted 505 kg, Björnsson shared on social media that 510 kg was his strategic choice, which allowed him to reserve the energy for the remaining five events of the competition.
In addition to this, Björnsson also impressed the audience with his show-stealing performance at the Giants Live World Open, especially in the Power Stairs and Front Hold events. He is now considered the third-most decorated strongman in history with 32 international wins and 129 world records.
Hafþór Björnsson’s Training and Strategy
While most of the general audience might think that one requires just deadlift technique and training to lift the weight, let me tell you that weight lifting requires immense power that should be well-coordinated with techniques. As per Hafþór Júlíus Björnsson, he had the following strategy before he lifted 510 kg in the competition.
Hafthor Bjornsson’s Warm-up Strategy:
– 70kg for 5
– 120kg for 3
– 170kg for 2
– 220kg, 270kg, 320kg, 370kg – all singles
Main Stage Weights:
– First at 420kg
– Second at 470kg
– Final attempt: 510kg
He also shared in a video post saying, “People have been asking me, if 510 is light, will you go heavier? And the honest answer is no. I won’t go heavier. I want to win the whole show. I have five events left after that lift. It’s about being smart.”
Similarly, Hafthor Bjornsson’s powerlifting achievements include 129 world records in deadlifts, squats, presses, yoke lifts, and many more.

I understand, I know nothing in comparison, just from what I see.”

Pankaj Kapoor’s Take
It is absolutely unbelievable to see how a human can lift a 510 kg weight. As we are all familiar with how Hafþór Júlíus Björnsson looks, 510 kg is still a massive weight, but considering his body structure, he might have felt comfortable lifting the weight. Not only this, he broke his previous record of 505 kg deadlift, rewriting his name in the history books.
I feel satisfied with him achieving what he is really meant to be, watching his character, Gregor Clegane, in Game of Thrones.
