Talk about baby weight: Facebook founder Mark Zuckerberg shows off new workout routine featuring his new personal trainer, his daughter

  • Mark Zuckerberg's latest videos show him working out with his daughter
  • He completes a round of pull ups and push ups with her strapped to his back
  • He says his toddler daughter is  'easily the most demanding trainer I've ever had' 

Facebook co-founder Mark Zuckerberg debuted his new workout routine today, featuring his new personal trainer and favorite weight vest — his daughter Maxima. 

In a pair of videos posted on his personal Facebook page, Zuckerberg can be seen, presumably in his Palo Alto, California home's gym, doing a set of pull ups and push ups with his 16-month-old daughter strapped to his back. 

Zuckerberg accompanied the videos with the comment, 'As soon as I finish she yells "More! More!" Easily the most demanding trainer I've ever had.' 

The 32-year-old social media exec and philanthropist banged out five pull ups and 14 push ups in the videos with his daughter cozied up to his back in a baby carrier, much to the delight of Facebook users around the world.   

Many users praised the daddy-daughter time, commenting that the cute clips reminded them of workouts they did with their own children or with younger siblings. 

'Mark this is awesome! I've done pushups with my daughter as well and she loves it and always asks to do more,' wrote user Pavel Ponomarenko. 

'You are a cool Dad Mark! haha. Your little girl is like come on Daddy do more pull ups. Such a cute video,' enthused Andy Sipos.

But, an overwhelming number of Facebook users were quick to note the way Maxima's unsupported head appeared to loll back and bounce as she hung off Zuckerberg's back while he pumped out the pull ups and push ups.

'Might wanna take a couple million and invest in a neck support for max, bud, other than that good job,' wrote Dave L Ross. 

'My pediatric doc told me that the Head should not tilt backwards like this in a Toddler ... May lead to shaken baby syndrome ... Mark Zuckerberg check with your wife,' warned Facebook user Vinatha Kumar.

'Her head and neck are hyper-extended and her head bobbing around is not good for her brain inside the skull,' wrote Debbi Postas. 'Why not just sit her in a seat or playpen to watch you?' 

Last January, in a Facebook Q&A on his wall, Zuckerberg told a curious Arnold Schwarzenegger that he works out at least three times a week, usually when he wakes up in the morning.    

'Staying in shape is very important,' Zuckerberg wrote. 'Doing anything well requires energy, and you just have a lot more energy when you're fit.' 

Zuckerberg and wife, Dr. Priscilla Chan, are currently expecting a second child, another girl.
