Hi S.,
I belong to the LA fitness on Coit/GB and have really loved it. The kid care was my main reason for joining (i was comparing to 24 hr Fitness as Lifetime was too far for me.) The people working there are really sweet and patient with my little girl, who is going through separation anxiety. The staff is very nice overall. When I investigated last summer, it was cheaper than other gyms as they are trying to boost membership. They would allow you to go month to month at first, I think, to try it out. You can also just ask for a 1 week pass to try it. There is a lot of room for negotiation on gym contracts, I have found. The kid care is free w/ membership. The classes are great. It doesn't have quite the amenities of Lifetime from what I've heard, but if you are just looking for cardio machines, lifting, classes, and a pool, you can't go wrong w/ LA Fitness. Good luck whatever you decide!
