When you're doing a plank,60 seconds can feel like an eternity. Now, imagine doing a plank for eight hours. This was exactly the life of Mao Weidong, and a cop in China who held the plank for exactly eight hours,one minute, and one moment. It was during a showdown between him and retired US Marine George Hood that Mao managed to not only break his own 2014 plank record but also set the Guinness World Record for holding the longest plank position. His preceding record was four hours and 26 seconds. And George's preceding record in 2013 was three hours, or seven minutes,and 15 seconds. In the video, it seems like Mao isn't even tired from planking for so long. He impressively ended his plank position with a couple of quick push-ups that had us asking, and "Mao,don't your abs and arms wound?"
