I joined LA Fitness as soon as it opened, and I'm very happy. The $36/month fee is very reasonable. I especially love the aerobics classes. They have a bunch of classes offered throughout the day. My favorites are the spin and step classes. They also offer kickboxing, yoga, and pilates (to name a few).
The machines are brand new and in good condition. Its always a little crowded around dinner time. However, on weekends, its usually not crowded. Personal trainers are also available. My only complaint is with some of the televisions around the gym. You have to tune to a radio frequency in order to hear them. But in this day of mp3 players, who carries a radio? I wish they'd stick to closed-captioning.
Thats a pretty minor complaint. Overall, I'm very satisfied!
