I relize this is an older post BUT I got to give my 2 cents on the whole gym thang.
Women's Gym
The equipment is smaller, almost everyone is fat, pretty easy to go to. Though I found the aerobics class disturbing, "AND SMILE NOW LADIES!"
24 Hour Fitness/Bally's
I have causght women actually checking thier make-up there. What is this a singles club

Plus I was generally unimpressed with the staff can anyone over 12 work there
Personal Trainer
Awesome but costly. I had a really funny,attractive, nice, intelligent one for awhile and I lost the pounds. Then she went back to college and well the next one just sucked. I paid her to leave me alone
Private Gym
Select company, smaller so equipment is limited, is almost always empty when I go. The guys sometimes make adjustments to the machines that make it a workout to put back. But I think this is my preference besides working out at home(PLUS LESS GERMS

think about it and when ur at 24 hr try not to gag)
So there it is,
