According to Guinness World Records, the longest time any man has held the planking position -- at any age -- is 8 hours, 1 minute, set by China's Mao Weidong in 2016.
"It's quite grueling. And I don't really practice it (planking)," Steinfeldt told the Lakeshore Daily News. "(Holding a plank is) is "too boring to practice. So it was stressing a few places I usually don't get stress. But I'm recovering."
Steinfeldt said he planks to motivate others to overcome challenges, WCCO reported.
