An update. After the second week I stopped attending. The instructors were great, however I was working with a previous rotator cuff injury. I hoped they could give a viable option that worked. They did some modifications, however it further aggravated my old injury. I enjoyed the portions of the class that didn't aggravate my injury. Overall, the participants range from all ages, sizes and fitness abilities/inabilities. The cost...well you'd save $50.00 by joining their gym and have access to unlimited classes vs. being able to only attend the "Fitness Challenge" class. You'd still get the nice attentiveness from the staff/owner, be able to have time flexibility, and select your class(es).
