I like doing pushupsΒ Β and pull ups because even though I have the equipment and a full weight rack in my cellar , I always assume that it could be taken away. I always picture scenarios -- alone in the woods with no equipment or nothing else; try doing a 500ib squat or 300ib bench press then; your muscularity wouldn't even be suited to that environment, it would be dead-weight and quickly absorbed as fuel. & if you've ever used steroids or are currently abusing hormones, your ***** would shrink to a walnut; you've already damaged your body's hormonal system and are now a man reliant on exogenous substances. you're dependent. I don't want to be dependent. I want to climb up a branch and pull myself up 20 times if I have to, or push my body's weight 100 times , I don't need a piece of steel , I need a piece of deer lung. & as the cell closes in, the newspaper with water bags make great dumbbells. just be sure to get your vitamins. & watch out for predators in the night
