At the urging of Harry’s wife and doctor, 50 year old Harry finally made it to the gym. After consulting with one of the trainers, Harry decided to try out a steep treadmill. “Ok”, said the trainer “I’m going to set it for ten minutes, if you want to go longer just press start again.” At first Harry was doing fine but after 5 seconds he started getting tired, and after a minute he jumped off gasping for breath. Walking to the side to sit down, he passed by a friend of his. “Man”, said Harry. “I could barely last a full minute on that treadmill.” “Alright alright”, said his buddy, “no reason to brag!”
