Been working out for nearly 40 years now and lately this has become one of my pet peeves. Work out with primarily free weights mostly using dumbbells. Super set with various weights and generally only rest 30 to 45 seconds between sets and always re-rack between sets. The problem arises when some millennial with his iPhone and earplugs gathers a set of 4 or 5 dumbbells around his bench then spends the next 15 minutes texting and not working out. I go to the rack for the next set and low and behold it is damn near empty which screws up my work out. Based on the physique of these little snowflakes, they should leave the iPhone in the locker and spend the time actually working out rather than friending on Facebook. At times when my frustration reaches a certain level, I ask them are they here to work out or play on there phone, If the latter please re-rack the weights so someone can put them to good use. I usually get this indignant look that I am invading their precious space but they usually wind up re-racking. Due my job responsibilities I need to be available at any time but there is one place I never take my cell phone with me and that is in the weight room and wish they would do the same.
