Both strongmen are set to meet in Dubai next week when they will go toe-to-toe in the ring.
The fight was meant to take place last September but Hall had to pull out due to a bicep injury.
The fight will be the heaviest fight in the history of boxing when the big guys meet in the United Arab Emirates.
Bjornsson, who plays Thor in the hit TV show Game of Thrones, said that Hall cannot pull out of their fight with an injury this time.
The 33-year-old posted a photo of his new physique to his 3.8 million followers on Instagram saying: “Saw Eddie today.
“He’s injury free so there’s no excuses to not show up on March 19th. The fight is on!”
People were impressed by the Icelandic’s body shape with one user saying: “I believe in you Thor! Go prove yourself. Been too long.
“We all know you are going to take care of business. Trust on your jabs and from there go on punishing. Good luck. The gods are with you.”
Another said: “Aside from the fight, you look like you’re the healthiest you’ve been in a long time. That alone is a win, congrats!”
A third added: “Good luck Thor. I’m sure all the hard work will pay off.”
Another user simply stated: “Don’t forget you have VIKING POWER.”
Friends of the two strongmen believe that Hall might have the edge on his opponent as he has too much raw power.
Despite who wins the match, it will surely be a good fight with so much power and talent on show and the pair will treat the Dubai fans to a heck of a fight.
