You probably don’t know that Tom Hoel held a plank for four hours and 28 minutes on May 22, 2015, setting a world record.
You probably don’t know that this is the second plank record for Hoel, a 52-year-old Dane. His previous record of three hours and eight minutes, set in 2014, was obliterated by Chinese policeman Mao Weidong a few months later. Weidong planked for four hours, 26 minutes. My longest plank is three absolutely miserable minutes.. :D
