after being in a filthy gym, filled with iron and equipment, I say you don't really need to stay in one after you reached your goals... I mean, it's a great place to gain new muscle but after that.. meh
I'm now in one of these homo gyms, pay less, much cleaner, girls are much more good looking,etc
I train about 3 times/week and it's more than enough to maintain.
steroid abusers start to become a bore after a while
