A 57-year-old man set the world record for holding the longest plank at 5 hours, 15 minutes, and 15 seconds.
After two whole hours, he says, "I'm into the uncomfortable stage now." That's a pretty bold statement from a man who has already been continuously exerting his core muscles for the amount of time it takes to view two whole episodes of a television drama. And he still has three more episodes to go. (Thinking of extreme planking in terms of TV episodes is the only way I can wrap my mind around it.)
He describes his strategy by explaining, "I look for every bit of distraction I can get." So actually maybe it would be helpful to throw on a few episodes from the second season of Parenthood in his line of vision. And now it doesn't seem that bad.
