Query: Well thought-out and presented.

The DVD is split into two parts: Nordic walking for beginners and traditional ski walking for more serious training. The program starts by `walking" a beginner through the new activity. I found this easy to follow and replicate outdoors. The format has been well thought out. Even a long time skier will learn new tricks to improve dry-land training in the second section of the disk.
