It’s been suggested that the billionaires could lock horns when Tesla owner Musk called out Facebook founder Zuckerberg on social media in June.

Judging by these latest images Musk will have his work cut out against Zuckerberg

Some think it could be a joke but Zuckerberg appears to be taking things very seriously as he displayed his ripped figure in a gym picture alongside Adesanya and Volkanovski.

Adesanya and Volkanovski flew to Zuckerberg’s home in northern California after UFC 290 in Las Vegas on Saturday night before getting to work with the Meta head on the mats.

Zuckerberg displayed some impressive chiselled arms and a six-pack in the pictures, commenting: “It’s an honour to train with you guys.”

While he’ll never reach the standards of those he was training with, Adesanya was impressed with what he saw, captioning the Instagram post: “[Trophy emojis]. No fugazi with Mark [shark emoji]. This is Serious Business.”

Zuckerberg’s already displayed his combat skills having won two medals at a Brazilian Jiu-Jitsu tournament earlier this year.
