Elon Musk, the CEO of Twitter and Tesla, among other major companies, has been in the gym training and staying alert in case the reported fight with Meta CEO Mark Zuckerberg comes to fruition.

However, Musk admitted Monday that he might have to work a lot harder to make it to a mixed martial arts arena.

Podcast Lex Fridman posted a photo of himself, Musk, UFC legend Georges St. Pierre, and MMA instructor John Danaher during one of their training sessions.

«So much fun! The obvious conclusion is that I need *much* more training,» Musk tweeted in response to the image, adding that it was an «honor» to be among those men.

The training sessions have come before a rumored fight between Zuckerberg and Musk. St. Pierre tweeted to Musk late last month volunteering to train Musk.

«I’m a huge fan of yours and it would be an absolute honor to help you and be your sparring partner for the challenge against Zuckerberg,» St. Pierre tweeted, to which Musk agreed.

Musk, who also owns SpaceX, previously admitted that he did not exercise regularly, though he previously tweeted that he trained in «judo, Kyokushin (full contact) and no-rules street fighting.» Zuckerberg has trained in Brazilian jiu-jitsu, a self-defense martial art, for more than a year and won an amateur tournament.

The idea for the cage fight began on Twitter on June 20, when Musk and other users of the platform were discussing Meta and developing a Twitter-like competitor.

Musk then offered to settle the competition with Zuckerberg, owner of Facebook and Instagram, in a cage fight. Zuckerberg reportedly accepted the challenge.

For what it’s worth, Threads was released on Wednesday without a fight taking place.

UFC president Dana White later confirmed that the two billionaires were «absolutely serious» about a potential fight.

White told TMZ Sports that the celebrity contest could be «the biggest fight in the history of the world.»

«Bigger than anything that’s ever been done,» White continued. «It would break all pay-per-view records. These guys would raise hundreds of millions of dollars for charity. You don’t have to be a fight fan to be interested in this fight. Everyone would want to see it.»
