Mark Zuckerberg is fully committed to his action-hero exercise routine. The Meta CEO, gave followers another look at his increasingly intense fitness lifestyle after posting clips from his Memorial Day “Murph” workout on Instagram Monday. What started as a surprising hobby for the Meta founder has evolved into a serious commitment to CrossFit, Brazilian jiu-jitsu, and MMA-style training.
Zuckerberg tackled the brutal Murph Challenge, one of the most respected endurance workouts in CrossFit culture. The workout honors Michael P. Murphy, the Navy SEAL killed during Operation Red Wings in Afghanistan in 2005. Murphy was posthumously awarded the Medal of Honor, and the annual challenge has become a Memorial Day tradition for athletes, military members, and fitness enthusiasts worldwide.
Zuckerberg shared clips of himself grinding through the workout while wearing a weighted vest. He does this “every Memorial Day as a tradition to honor those who defended us.”
The Murph Challenge is anything but casual gym content. Participants complete a one-mile run, a 100 pull-ups, 200 push-ups, 300 squats and another one-mile run. Traditionally, the entire workout is performed while wearing a 20-pound weighted vest.
According to previous posts, Zuckerberg has completed the challenge in under 40 minutes, a time many experienced CrossFit athletes would consider elite for a non-professional competitor.

The billionaire executive has trained extensively in Brazilian jiu-jitsu and mixed martial arts, even winning medals at a jiu-jitsu tournament in 2023. Online, fans started calling him “Shredded Zuck.”
His wife, Priscilla Chan, also became part of the conversation after Zuckerberg revealed he had installed an MMA-style fighting cage in their backyard. Zuckerberg appears genuinely invested in the discipline that comes with combat sports and high-performance training.
