The whole is really fun and brings a sweat. Movement to music, a great thing. Unfortunately, the "Progress Summary" bugged. At first we went, but then was the end. Xbox freezt everytime you want to look. Very sad, is all but (at least for us it is so) a good bit more motivation. To date, it seems to have not solved the problem. I wonder if it is still working? It would be nice in any case.
