Joe Rogan was impressed with Mark Zuckerberg’s viral MMA training video shared on Instagram, Saturday night. Writing a comment under the Facebook founder’s post, Rogan remarked that he was “happy” to see his interest in the sport.

“One of my training partners, @khaiwu, is making his debut on @ufcfightpass tonight,” Zuckerberg captioned the clip. “Looking forward to a great fight.”

Rogan, who works as a UFC commentator in addition to podcasting, wrote in response: “This is great! I’m so happy to see this. Training looks solid too!”

Zuckerberg had recently revealed his interest in MMA during an appearance on The Joe Rogan Experience, telling the comedian that he’s been working with Dave Camarillo.

“It really is the best sport,” Zuckerberg said at the time. “The question isn’t, ‘How did I get into it?’ It’s, ‘How did I not know about it until just now?’ From the very first session that I did, like five minutes in, I was like, ‘Where has this been my whole life?’ All right. My mom made me do three varsity sports and my life took a wrong turn when I chose to do fencing competitively instead of wrestling in high school or something.”
