Delivery
It comes with a DVD and two cards with pictures of the exercises are included. The cards are very practical and make the practice range is very good. The DVD shows the exercises also, but just on the move. The image quality of the DVD is below average. I looked at the DVD only briefly, because I exercise enough cards for guidance.
