Zuckerberg muscles in on tech bros' extreme fitness regimes

You've got the billions, you've got the global brand domination - what comes next? An extreme fitness regime, of course.

Mark Zuckerberg has revealed he has taken part in an intensive challenge in which he ran a mile, did 100 pull-ups, 200 press-ups and 300 squats before running another mile, all while wearing a 9kg weighted vest.

The Facebook founder, in a post on his own page, said he had completed the "Murph challenge" in 39 minutes 58 seconds. One user said this would put him in the top 1% of those who had completed the event, which is named in memory of a US navy seal who was killed in Afghanistan.

Complimented on his pull-ups, the multibillionaire (worth £93bn or so at present), said: "The last mile run when your legs are torched from the squats and your heart rate is pegged is pretty brutal too."

Other recent posts from the 39-year-old celebrated the medals he won in his first jiu-jitsu tournament (gold and silver) and a sub-20 minute 5k. "I actually stopped running for a while and got stronger from [mixed martial arts]. Then I ran for about a month before this race and realized I was faster than before," Zuckerberg told an impressed commenter.
