The workouts really work on me. So I am interested in the creator behind it. Very nice and inspiring story, told calmly. I like the theory behind the workouts, and the analogy she draws to life. You might say it is cheesy, but I do feel that the only way that you can hold on to workout (or anything) for long is to truly connect it to a higher purpose. That way, a workout is not merely sweating for 6o minutes; you are aware of your status, "how am I and which phase I want to be in today"? And, you have the inspiration to live an all out life, that way each day is part of it, and it is your way of living.
I know some of it might be marketing, but the spirit is taken.
