"Anybody can do what I do," Hood said in an interview with CNN. "Everybody has to start somewhere.

"Every tree that's planted has roots. Once that tree is planted and those roots start to grow, whether it be 30 seconds or a minute or five minutes or an hour [of planking]

"You start repeating the process and taking care of your tree, it will grow and you will improve and you will actually get better."

Mr Hood's preparation included four to five hours of planking per day, including an incredible 2,000 sit-ups, 700 push-ups 500 leg squats and 300 arm curls. Daily.
