I was doing a workout in my building today where I had two 5lb ankle weights, 40 lbs vest, and a 50 lb bag that I lunked over my shoulder while walking up and down the stairs. One of my neighbors saw me do this and he said "you know what would be a great place to do that go to(neighboring city's city hall) the stairs are great I used to do the same thing you are doing when I was fit there!" Shit you not this guy had to weigh 300lbs+. The guy was probably in his late 50s and my only guess is he stopped, if he ever even started, working out and ate the same amount of food and got fat as fuck over the years. I thought to myself while doing a set that I will never be like him.
