Hafthor Bjornsson is continuing his training after defeating Eddie Hall in epic grudge match in March via unanimous decision in a bout named ‘the heaviest boxing match in history.’

After losing nine stone in his journey from strongman and actor to becoming a boxer, he is continuing a gruelling workout routine which is seeing him go from strength to strength.

The Icelandic brute has claimed he can perform 500 crunches in a row and has released a video of himself allegedly doing so on his Instagram page where he has amassed over 4.1 million followers on the platform.

His video shows him doing crunches, with his work our mat drenched in his sweat as he writes the numbers on the video of him reaching and surpassing 500 crunches… allegedly, although it would take a brave man to argue with him.

Boasting about his ability, he posed the following question in his caption: “How many crunches can you do in one go? I used to get cramps after like 50…”

The 33 year-old defeated his gigantic rival and former world strongest man Hall after he had three fights to prepare himself for the bout.

However, his attentions appear to have turned to the biggest fish of all, Tyson Fury, with the pair exchanging words online, leaving fans drooling at the prospect of a spectacle between two heavyweights.

‘Thor’ has claimed that talks were underway with the heavyweight champion, who insists he is retired, for an exhibition bout, although Frank Warren, Fury’s promoter, has disputed that.

Warren himself said: “There’s lots of things being said at the moment, but to be honest nothing has been done.

“Nothing will be done until I sit down with him. He’s got his tour at the moment, so he’s travelling around the country.

“Once that’s done in a couple of weeks’ time, he has a little break in-between, so we will sit down then and have a chat.”

Although he retired after knocking out Dillian Whyte at Wembley back in April, he fuels talks with the potential of an undisputed heavyweight clash with the winner of the rematch between Oleksandr Usyk vs Anthony Joshua.

Whilst Warren and Fury are yet to really enter the exhibition bout side of boxing, they both understand the demand that’s there for them and could be open to venturing into it in the future, although fans would surely prefer an undisputed heavyweight championship bout first.
