the workouts, schedule, and price are great! You wont be able to find another gym that offers as much variety and classes at the monthly rate that JAB offers. they offer everything from boxing to yoga and have multiple classes running at the same time. i can honestly say that if you want to push yourself JAB will also kick your a$$.
the location happens to be a little out of the way, but for all it offers its worth the drive. and yes, the instructors for boxing are a little rough. most of them have competed professionally, so yes it is a little bit of a boys club but they have fun and dont take things too seriously. if you are to sensitive and cant handle the rougher classes then you can always stick with yoga.
