I started at JAB in August on a Groupon and I love it. This is the first time in my life I've worked out regularly - 3 - 5 times a week. The classes are fun but also hard work and the instructors keep you moving. I never tried anything even remotely close to this before but felt immediately comfortable and jumped right in. Instructors and fellow classmates are helpful. The overall attitude of the gym is a bit irreverent and I wouldn't want it any other way. Staff isn't snobby or stuck-up like some at the big chain gyms tend to be. I actually look forward to my workouts - something I never thought I'd say!
