EDDIE HALL has fired a warning at Hafthor Bjornsson ahead of their bout in September.
The strongmen will share the ring later this year, in what has been dubbed the 'heaviest boxing match in history'.
Bjornsson, 32, took to Instagram earlier this week to show off his hulking figure.
But, unfazed, Hall has put out some intimidating content of his own.
The Brit, 33, took to Insta to share a video of himself going through drills in the ring.
Hall looked sharp and, by his standards, lean at 352lbs as he was put through his paces by a trainer.
He also warned: "Thors F****d".
And British WBO cruiserweight champion Lawrence Okolie was impressed, commenting: "Looking loose and powerful 😈✊🏿."
Not everyone feels the same, however, with Hall having had his skills criticised by Joe Rogan.
The podcaster and UFC commentator blasted: "That’s not good. Right away we’re seeing that we have a real problem. Yeah, this is terrible.

"He’s very rudimentary, but also you see that his body is very stiff. Looking at him sparring there, he’s just not moving so good
"This is super stiff. He’s throwing these punches with his arms. These are arm punches, almost like he shouldn’t be hitting things."
But Hall graciously took the comments on the chin, responding: "I love Joe Rogan, I absolutely do love Joe Rogan
"Look man, people can speculate, they can make assumptions, they can guess, they can do whatever they want, but I’m knocking Thor out.
He’s an experienced guy, he knows what he’s talking about, but he doesn’t know the full picture
Eddie Hall on Joe Rogan's criticism
"There’s no doubt in my mind. So, people can say whatever they want.
"I take no offence to Joe Rogan’s comments. He’s an experienced guy, he knows what he’s talking about, but he doesn’t know the full picture.
"You look at a few clips, you can’t make assumptions from that.
"It doesn’t bother me in the slightest, it doesn’t put me off. I hope it gives Thor more confidence, because he needs it.
"He’s in deep trouble. And I’d still love to go on The Joe Rogan Show and tell him a story for everyone to hear."
