I have been going to gyms for years and since the 90's there has been a "health club" push. I can understand to a degree not wanting the place full of juice monkeys, but they go out of their way to make serious lifters feel unwanted. I have actually found body builders to be the most helpful people at the gym.
Gyms make most of their money off the "donators" which are the fat chicks (or guys) that sign up after new years and then never show up. They either pay up front for a year or set up a contract with automatic withdrawls so that they can't change their minds. Ever wonder why you have to sign a contract at a gym? If you didn't they would not make any money. I have a buddy that used to own a gym and he said the majority of their members were "donators".
I digress, but the point is that dedicated lifters (juice monkeys) will be at the gym 5 days a week for an hour or 2 religiously. They want people that are going to pay and never show up, not guys that are going to beat on the equipment every day.
