Great gym on 14th Street near Kensington.
I've been a member since the beginning and I've tried some classes and personal training sessions. The classes are good, especially pilates! I love my trainer Wendy... she's a machine! The equipment is great, and machines feel high end. Plus, from what I have seen so far, there is a minimal amount of douchy gym rats there! ;)
Very nice change rooms and a couple of large showers.
I guess the only down side is the size of the classroom, which limits the number of people who can take the classes. I see that as a good thing, because I prefer smaller classes, but it may get crowded.
