Pole Dancing as an exercise?

I am a mother to a seven month old son, and I need to get back into shape. I always liked to dance and I think that pole dancing would be a unique and new way to try to work off some extra pounds as well as spice up the bedroom occasionally . I am wondering if it has worked for anyone else? I also think it would be a fun way to hang out with some friends too get a group together and learn. In my area there are no cles, but I have seen commercials for flirty girl fitness, Carmen Electra's as well as Kendra pole dancing. Anyone have any experiences with these? Another question does anyone know where to find cheap discounted poles, and not no 115.00, I just feel that's too much to spend just to workout, seeing as how I am not the only one in my family anymore. Any help is appreciated thanks!!
