It seems that Elon Musk is really serious about a duel with Mark Zuckerberg and is already preparing for the upcoming competition. On his Twitter, he reported training with Lex Fridman, who is known as an artificial intelligence researcher. He also practices Brazilian jiu-jitsu.

“Had a practice round with Lex Fridman tonight,” Musk wrote.

Instead, Fridman expressed admiration for the billionaires’ interest in martial arts and confirmed reports of training with Musk. He also posted a video of him practicing jiu-jitsu with the CEO of Meta.

“Here’s a highlight video of Mark Zuckerberg and I training jiu jitsu. I look forward to training with @elonmusk as well. It’s inspiring to see both Elon and Mark taking on the martial arts journey,” noted Lex Fridman.

By the way, Canadian sportsman and specialist in mixed martial arts Georges St-Pierre offered Elon Musk his services for preparing for a duel.

“I’m a huge fan of yours and it would be an absolute honor to help you and be your training partner for the challenge against Zuckerberg,” the athlete wrote.

The CEO of Tesla agreed to this offer.

“Okay, let’s do it,” he replied on Twitter.

Recently, Elon Musk challenged the CEO of Meta to a cage match. Mark Zuckerberg, in response to this, asked to send the location for the duel. Musk proposed a fighting cage from the UFC in Las Vegas, called the Vegas Octagon.

UFC Ultimate Fight Club president Dana White said he had a conversation with both billionaires, and they are “absolutely serious” about the fight. Instead, Elon Musk’s mother forbade him to fight.
