Hafthor Bjornsson sent social media into a frenzy last month when he set a new world record of 501kg for the deadlift.

Prior to this, the record was held by Eddie Hall – the man who is set to face Bjornsson in a boxing fight in Las Vegas next year.

Now, side-by-side footage of the pair lifting has emerged and it shows how ridiculously strong the Icelander really is.

The video shows how comfortable Bjornsson was at 420kg and 465kg, while Hall is clearly battling through the pain, dropping to his knee on both occasions.

It also shows Hall nearly pass out after his incredible 500kg lift, and ‘The Beast’ recently revealed he thought he was going to die following, at the time, the world record lift.

He said: “They put an ECH (heart sensor) on me to try and get a gauge of what my heart was doing, they couldn’t get one. By the fourth time the paramedic is saying that his equipment’s faulty, you know it’s not faulty and that it’s you.

“It was at this point that I realised I was going blind. I lost the vision in the centre of my eyes, that’s when I got quite scared. I just laid down on my back and stared at the ceiling. I thought this is where I’m going to die.”

The video also shows Bjornsson’s reaction to his 501kg lift and, remarkably, he is completely unfazed as he celebrates the achievement and his new world record.

Of course, it’s worth noting Hall’s lift came at the end of a gruelling competition, whereas ‘Thor’ set the record at his home gym in Scandinavia.

Fans are excited to see the bitter rivals step in the ring together for the fight billed as ‘the heaviest boxing match in history’.

While an official date and venue are yet to be confirmed, Bjornsson revealed on his Instagram page that the fight will take place in September 2021 in Las Vegas.
