I joined, however, despite the incredibly nasty head membership staff person because the classes were so interesting: mat pilates, karoake spinning, and a favorite (much to the surprise of people who know me), cardio-striptease.
Unfortunately now Crunch has been bought by Bally Fitness. While this has expanded the venues (for which I am pleased), it also means the interesting classes are gone, and I don't plan on signing up here again.
Pros: Formerly classes
Cons: Classes gone, Nasty membership ppl, Really loud music
