What are you thinking of -- CD? Or running a weekly WW or SW class? My favourite class ever was Rosemary Conley! I don't know whether they have one in your area, this one I used to go to the leader did a great aerobics work-out every week. She really filled the hall and gave you huge discounts if you went twice a week. I'm just thinking if there was already lots of SW and WW, maybe RC would be a route in. With CD you need to ask your orginal CDC to sponsor you to apply, think you need a BMI under 30, and then you have to go on two one-day courses.
