Meh.
Bathrooms: dirty. Clogged toilets, broken stall doors. Empty paper towel and toilet paper dispensers, empty soap dispensers, broken hand dryers, and slippery puddles of water everywhere.
Towels: Sometimes available, sometimes not. Hope you brought your own!
Equipment: Generally meh. There's only 1 real squat rack in this entire gym (!) -- Southside, which isn't even a 'Signature' club, has at least 4. There's not enough barbells for every bench. Many ellipticals are half-broken (destroyed resistance mechanism). People leave weights everywhere, and while it's not the staff responsibility to constantly clean up, you'll need to go on a scavenger hunt to find the weights you need. I don't use the machines, but I'm not hopeful for these given the poor upkeep in general.
Pool: The pool is sometimes closed, never with advance notice on the website, so you might get there and just find out it's closed.
This is probably the crummiest gym I've belonged to, although $40 is a lot less than I'm used to paying. Also, the other LA Fitness gyms in Pittsburgh are better.
