I tried the Pilates Studio as an experiment, I’m sticking around because of the good vibes.  The instructors are all very knowledgeable, as well as being cheerful, positive, encouraging and nurturing in their roles.  If you have pain issues, asymmetries, and other bodily weirdness, they’re all great at accommodating your limitations and helping you find movements you can do instead of forcing yourself into poses that hurt.  The cost is higher than a standard gym membership, but I’m getting such good instruction and encouragement that it’s worth it.
