The audio tape was great for 30-minute session. You listen and do the exercises on one side one day and the other side the next. That way you do the hour of active exercises over two days.
If you do it with the CD you get to about half way of forming the energy ball. Follow that with the harvest of the chi. This makes it easy to follow the exercises since you don't have to watch the clock. You are guided to the next exercise.
