Zuckerberg recently tore his ACL while mixed-martial arts training.

But prior to the injury, the billionaire had a rugged routine, according to Business Insider.

Usually around 8.am., Zuckerberg started every morning checking his phone.

In the past, he had run about three times a week.

Instead, Zuckerberg does three or four jiu-jitsu and MMA sessions weekly ahead of a potential “cage fight” between himself and Musk.

He trains with MMA fighters a few times per week.

And Zuckerberg does strength and conditioning work as well as mobility training.

The 38-year-old has never revealed what he eats for breakfast.

But Zuckerberg has admitted to eating 4,000 calories due to his brutal training program.

In July, he also revealed a McDonald’s order on Threads, his X, formerly Twitter, competitor.

Zuckerberg said his fast food meal consisted of “20 nuggets, a quarter pounder, large fries, Oreo McFlurry, apple pie, and maybe some cheeseburgers for later?”

Still, Zuckerberg told Forbes in September that he tries to get eight hours of sleep, which he tracks with an Oura ring.

His potential fight against Musk, which had already simmered down after months of negotiating terms for a bout, will have to wait even longer.

Zuckerberg recently underwent ACL surgery, which means he’ll be out for at least nine months.
