If you are thinking of buying this expecting a dance workout, buy something else. There is not much actual dancing, just isolation of movement in parts of the body. I wouldn't mind the small amount of dancing if the workout was good, but it's not. There is little to no instruction and some of the exercises seem as if they could lead to some serious back injuries. I know I had some pain in my lower back after doing this workout and I hadn't even tried to do all of the exercises since some of them did not feel right to begin with.
