I don't know about you, but I have a hard time watching movies for four straight hours without getting squirmy. And if I had to guess how long I could stay in the plank position without giving up, it'd be five minutes and probably ten minutes before I would start crying. 

Well, one 43-year-old man in Beijing recently shattered the Guinness World Record for staying in the plank position for a staggering four hours and twenty-six minutes. The previous record was three hours and eight minutes by Swede Tom Hoel. 

The new world record holder is named Mao Weiding, and he is also a member of the SWAT team in Beijing. Staying in the plank position becomes increasingly difficult as time goes on and tends to strain the muscles in your stomach and back.
