i forgot to mention that in addition to the classes you get personal advice from the instructors. you let them know what your goals are and they will help you reach them. and everyone in the classes are encouraging. right now we are doing a 90 day nutrition & weight loss challenge and everyone from all of the schools in the area has been very supportive.
you can take a free trial class to see if you like it. and i think there are sign up specials running now.
