No idea. Honestly, I've only ever been inside one, and it was only once. It is an old one, close to where I live now, and it is small and dingey. But lots of people I worked with in L.A. went to the YMCA downtown there and raved about it. So I guess it probably depends on each individual facility.
Will you take the anthropology quiz for me tomorrow?
(Oh I've studied and am ready for it, just thinking it might be fun to just once have someone take a quiz for me....)
