Mark Zuckerberg takes on the 'Murph Challenge' workout in a 20lb vest trends now
Meta boss Mark Zuckerberg has revealed his grueling workout challenge to mark Memorial Day in honor of fallen soldiers and 'those who defend us'.
The Silicon Valley titan took on the brutal 'Murph Challenge' workout which involved 100 pull ups, 200 push ups, 300 squats, and a mile-long run.

Zuckerberg may have secured his position as the fittest tech CEO in Silicon Valley as he was reportedly in the top 200 of tens of thousands of participants who have taken on the 'Murph Challenge' at the time of his post.
The exhausting challenge is named after Michael P Murphy, a U.S. Navy Seal who was killed on a tour of Afghanistan in 2005 who would regularly take on the brutal workout.

Some $2 million has been raised for its charity, the LT. Michael P. Murphy Memorial Scholarship Foundation through the challenge since 2014.
