Guinness record for plank set in Beijing

Four hours and one minute is long enough for a round-trip flight between Beijing and Shanghai, or for watching a long movie like The Lord of the Rings.

But how about maintaining your body in the physically demanding plank position?

Sounds impossible but George Hood, a fitness enthusiast and retired United States Marine, did it on Monday in Beijing, breaking the Guinness World Record for "longest time in an abdominal plank position", smashing his own previous record of three hours and seven minutes set in 2013.
