Mark Zuckerberg Shows Off Shredded Bod In Training Sesh With UFC Stars

Mark Zuckerberg is clearly taking his potential fight with Elon Musk seriously … he revealed Tuesday he’s already getting in training sessions with some of the UFC’s biggest stars — and he’s looking damn good while doing it!!

TMZ Sports has learned … both Israel Adesanya and Alex Volkanvski flew to Zuck’s crib in Northern California following Saturday night’s UFC 290 showcase in Vegas — and almost immediately, they got to work with the Meta honcho on the mats to prep him for a possible tilt with Musk.

The three obviously worked out for a while — ’cause check out the photos, they were drenched in sweat.

What’s even more notable about the pics, though, is Zuckerberg’s physique — the dude is jacked!!

The 39-year-old flexed some big pecs, chiseled arms, and a six-pack in the images. He also added in a comment on the pics, “It’s an honor to train with you guys!”

Adesanya, meanwhile, was impressed with the billionaire’s work … saying in his own comment on the photos, “No fugazi with Mark 🦈 This is Serious Business‼️”

Zuckerberg and Musk have not yet committed to a fight … but both seem dead serious about getting after each other in a cage later this year.
