Mark Zuckerberg TRAINS with Israel Adesanya and Alex Volkanovski

Meta CEO Mark Zuckerberg linked up with a couple of UFC champions for recent training on the mats.

Zuckerberg is a passionate MMA fan and has been seen at multiple UFC events in recent years. He had a VIP screening of a UFC Fight Night event last year that was headlined by Mackenzie Dern vs. Yan Xiaonan

"No fugazi with Mark," Adesanya tweeted Tuesday. "This is Serious Business!"

Zuckerberg and business billionaire Elon Musk have teased a potential cage fight this year, a notion that UFC President Dana White has taken seriously. Musk and Zuckerberg have both been spotted working out hard in anticipation of the probable confrontation.

Volkanovski defeated Yair Rodríguez in the UFC 290 event this past weekend. Adesanya is scheduled to return later this year against emerging rival Dricus du Plessis.

Zuckerberg has shown himself as a no-nonsense grappler; recently won his first Brazilian Jiu-Jitsu event.
