We had the same idea, I first thought to use that contest instead.
Edit: I jokingly call that show American Forearm Warrior.
My wife likes the American Ninja Warrior show. She keeps getting on my case on when I am going to sign up (and trust me I don't have any physical abilities that would make me successful). I gently mock the show all the time.... when I am not being sarcastic about her other shows - "Love Island" and "Big Brother". (sigh)
