I've been a member of all the gyms here in town. By far I like 24 hour the best, I have done some traveling and been able to use the 24 hour fitness in other states no problem. Just like any other gym you get the occasional DB's that walk around with the sole purpose of checking out woman, or dropping weights and grunting to show the gym just how b.a. baracass they are. 24 hour is always clean and they have tons of newer equipment that seems to be kept in good order. With health being the modern fad, they gym tends to get a bit crowded at peak hours. So my advise it to not go at peak hours unless you are forced to.
24 hour offers plenty of free classes, just make sure you get there an hour before the class starts and sign in for the class to secure your spot.
