I just switched gyms from a "posh" fitness club to a hardcore "Iron Jungle". The reason I switched was becuase I moved, and the new "old school" gym is much closer to where I live now. It is one of the oldest gyms in town, but still very popular. There is chalk, and many old machines, and there is no dress code and you can scream as loud as you want. Much different from the fitness club.
Its a really cool gym, and you get to know everyone, but, on the other hand, I kinda miss the fitness club that I went to. It was actually pretty sweet. It was the biggest gym in the city. Huge variety of free weights, EZ curl barbells of almost any weight which I really liked, every kind of machine that you could ever ask for, and many multiples of racks so you never have to wait for anyone. Huge cardio theatre with brand new cutting edge equipment. Not to mention the sauna, steam room, hot tub, free shaving cream, squash courts, tennis courts, pool, basketball courts, track, and juicebar. There was also a high abundancy of hot women there. There was also a lot of elderly people who went there surprisingly.
So, you can see what I sacrificed to move to the Iron Jungle, but I am happy with this gym. You feel much closer to the people there, and another bonus is that my gym membership is 1/2 what it used to cost me. So ya, the fancy fitness clubs are nice also, but I guess that you just get what you pay for.
