How is that even possible?

I joined a gym for a while so that I could actually go to the gym and just work out without having to actually work. Every time I tried to go to my studio and work out I would always end up showing someone how to work a piece of equipment or showing someone how to fill out paperwork. It always happened. This gym that I joined was, of course, one of those big open spaces with a ton of equipment and lots of meat heads. I can't even begin to tell you the bad form I saw with EVERY single man/boy in that gym. Yet, somehow, they all had bulging arms, giant leg muscles and from all the many times I saw them lift their shirt and check themselves out in the mirror and take pics (for what? to look at later?) they had pretty defined stomachs as well. How does this happen? Why do people get rewarded for doing things incorrectly? Here I am doing my job telling people how to do it the right way and most struggle just to maintain before we find the balance that works. But these guys get instant results for doing it all wrong. Makes me sick.
