1-2 hours a day of exercise is easy. You stop when you want to, and can take time off. There are literally machines that guide the exact path your weight takes so as to avoid injury. Weights are symmetrical and designed to be held and carried. Workout conditions are generally comfortable or at least tolerable. The likelihood of you dying or getting hurt cuz of someone else not knowing what to do in a gym is low to negligable. Meanwhile it's 4:41am, and you're going to be working for the next 8 hours on your feet lifting 80 lb things at weird angles in high humidity. Half of your staff may be Hispanic day laborers and not speak English, and the other half may range from the semi-literate to get-in-get-out experienced tradies who DGAF about your problems cuz they're only on site for 1 day. When they fail to nail a board in properly it falls on you, not a serious injury or anything but another scratch and bruise. And then you get to do the same thing tomorrow.
