I use the gym at the JCC but have never participated in the rest of the community center activities. The gym is pretty good. New equipment and never any wait but the room is stuffy and hot. The classes are where it’s at; nice instructors and great variety. Cons are that it closes early and isn’t open Friday nights or Saturday mornings for the sabbath. Also there’s usually only one class each evening so you really need to plan your schedule around it. It doesn’t compare to the Y or to nearby Lifetime Fitness but it’s cheap and has a great community vibe.
