What was a time you saw a fat hurt themselves doing physical activities? This includes but is not limited to martial arts, regular sports(basketball, football,etc), hiking, swimming, and surfing to name a few. I've trained with numerous fat partners who've gassed out from simply hitting pads. One guy in Judo was not only fat but smelled awful, like a combination of BO and tobacco. He got tapped out real quick by one of the fitter guys during randori, lol.
