The two strongman competitors have feuded for a number of years and the score will be settled in September 2021 in Las Vegas.
Hall has been cutting weight ready for the fight and he recently posted a transformation photo, showing himself in 2017 compared to now.
'The Beast' states that he was 196kg in the first image while he's now down to 163kg.
Hall noticeably has a six-pack now and will likely be much more agile in the ring at his lighter weight.
Bjornsson has also been cutting weight in recent months with the Icelandic tank updating fans on social media.
He has managed to drop from 206kg to 188kg meaning he has shed just shy of 40lbs.
Bjornsson broke Hall's deadlift world record earlier this year when he lifted 501kg at his home gym.
It was after the deadlift that Bjornsson made the shock announcement that a fight was in the works.
"CoreSports just offered me a seven-year contract, I have signed it already," the 31-year-old began.
"Eddie Hall has been running his mouth now for weeks and I know he has been given the same contract.
"So Eddie, I just knocked out your record. And now I'm ready to knock you out in the ring.
"It's time to put your fist where your big mouth is, and sign the CoreSports contract.
"I'm ready. Are you ready?"
Hall then quickly responded with: "1000 per cent I'm going to sign those papers.
"And you know why I'm going to sign those papers... it's not the money, it's not the dead lift feud we've got going on, nothing to do with that.
"It's because you called me a cheat at World's Strongest Man 2017.
"I can't put that to bed, I can't forget it. People may forget it, but you've never apologised.
"You think you should've won that year, regardless of the trophies or not, and you let people know that."
