- when people put their water bottle on a bench/machine that they are not even using
- people who do bicep curls by swinging their arms up and down without actually doing any curling
- when senior citizens engage in full blown locker room conversations while completely nude
- the need to slam your dumbbells to the ground after a set just so everyone knows how much you can put up
- individuals who enjoy repeatedly lifting up their shirt to view their abs in the mirror (even if they are not even doing abs atm)
- the smell of canned tuna fish near the desk where all the personal trainers hang out
