Faithful readers of ThePostGame might remember George Hood, the retired DEA agent and a former Marine who has set the Guinness World Record in endurance planking several times since his initial attempt in 2011.
Hood's latest record is mind-boggling: He planked for 9 hours, 11 minutes and 1 second to represent the significance of 9/11/01. Hood performed this challenge on Veterans Day aboard the USS Midway and made it a fundraiser for the Semper Fi Fund.
The previous record was 8 hours, 1 minute and 1 second, set in May by Mao Weidong, a policeman in China.
These marks are all the more stunning when you consider that Hood's first planking world record was 1 hour, 20 minutes and 5.01 seconds.
"The goal was always to set the new record at 9:11:01 to memorialize the heroic sacrifices of our veterans," Hood said in a statement. "This can never be repeated."
Hood, who will turn 59 in December, has also held Guinness World Records in endurance for jumping rope and spin cycling.
According to a press release, Hood burned 2,066 calories and his average heart rate was 88 beats per minute during his plank.
In addition to taking on his own challenges, Hood works as a personal trainer in Carlsbad, California.
