Wait a minute - wasn't Meta founder Mark Zuckerberg (39) always this lanky nerd who looked like he'd never seen the inside of a gym? However, “Zuck” no longer has anything in common with his former, untrained self. The 39-year-old has now posted a photo on social media showing him in top physical form – shirtless, with a six-pack and many muscles.

From lanky nerd to MMA monster, Mark Zuckerberg has undergone a remarkable transformation.

The reason? The upcoming MMA fight against Twitter boss Elon Musk (52). US media call the duel the "biggest fight of all time."

It doesn't look so bad for Mark Zuckerberg: The meta mastermind has experience in martial arts and masters Jiu-Jitsu. Musk's martial arts, on the other hand? Maximum street fighting level.

Mark Zuckerberg is getting fit.

So is Zuckerberg's latest post an attempt to intimidate the competitor? It could work because the 39-year-old presents his hard-fought athlete's body in the post and shows himself in the best company.

Israel Adesanya (33) and Alex Volkanovski (34) are the most successful MMA fighters at Zuckerberg's side. "No games with Mark, this is serious," Adesanya writes about the post, apparently meaning the planned fight against Elon Musk.

Zuck's response: "It's an honor to train with you guys."

The tech giants are walking their talk. However, the time and place have yet to be determined. UFC President Dana White (55) has already spoken to both parties about Las Vegas as a venue.

The favorite is – no wonder – Mark Zuckerberg. In May, he won gold and silver at a Jiu-Jitsu tournament. This Twitter clip shows how good he is:

Does Elon Musk need to start worrying?

And Elon Musk? He described his best move: "I do this move that I call the 'walrus.' I lie on top of my opponent and don't do anything."

In the meantime, however, the Tesla boss is also training. Zuck's good form spurs Elon on!
