I've had a membership there for a couple of years. I'll admit that I can come up with any excuse under the sun not to go to the gym. When I DO go, though, it's very enjoyable.
If I go at the right time of day, it's mostly the over-55 crowd, so I feel right at home in my baggy work-out clothes and huffing-and-puffing like an old steam engine. Locker rooms and showers are clean. The equipment at my gym seems to be in good condition. There's an area with a bunch of different machines that you use in order for a certain amount of time; it's supposed to give you a complete workout in 30-40 minutes.
The personnel there are very nice and helpful. At least at my gym, there aren't any classes like Zumba or anything organized. You can get a free "assessment" when you join, but you're pretty much on your own. You *may* be able to pay for individual training but I haven't seen anything like that. They actively discourage loud behavior like "screaming" or "grunting" like you may hear some of the serious weightlifters do at more serious gyms.
I think some locations are open 24 hours.
You can't beat $10 a month. There's some sort of yearly $35 charge, too.
