Mark Zuckerberg looks in insane shape as he trains with UFC champions ahead of Elon Musk fight

Fans are alreading fear the worst for Elon Musk if he does step in the Octagon with Mark Zuckerberg after seeing the Meta chief's incredible physique.

The pair of billionaires have agreed to fight inside the cage after trading jibes on social media in an exchange where Tesla CEO Musk did his best impression of UFC legend Khabib Nurmagomedov and asked Zuckerberg to "send me location".

UFC president Dana White is onboard and has been involved in talks with the duo, who he claims are "dead serious" about a bout that could be "the biggest fight ever in the history of the world" and do crazy box office numbers.

It's even been proposed that Musk and Zuckerberg do battle at the iconic Colosseum in Rome, with White and his people having conversations with the government officials in Italy.

However, the general consensus is that Musk, who is 13 years older, has absolutely no chance against Zuckerberg.

And many have formed that opinion after seeing 'Zuck' look in insane shape in recent photos posted to his Instagram.

The Facebook founder has been training with Israel Adesanya and Alex Volkanovski, who are part of the same City Kickboxing team based in Auckland, New Zealand and hold the UFC middleweight and Featherweight championships respectively.

Adesanya and Zuckerberg both shared the snaps on Instagram, with the 39-year-old commenting: "It was an honor to train with you guys!” after the Last Stylebender said it was "serious business".

Zuckerberg has been training in MMA for about two years and recently participated in his first tournament and winning a gold and a silver medal in two different disciplines.

Musk, who recently linked up with the iconic Georges St-Pierre, might have the bigger frame but Zuckerberg would appear to be the clear favourite because of his combat sports experience.

In a recent interview, Volkanovski, who defended his title against Yair Rodriguez at UFC 290, said he is backing Zuckerberg all the way and even offered to corner him.

In the latest in the situation, Musk threatened to sue Zuckerberg over similarities between the new Threads app and Twitter - while he then proposed a “literal dick measuring contest” in a bizarre turn of events.
