I have the book right here; let me give you a brief run down.
It is softcover, about 130 pages of info, (and some advertising for his stuff) and lists about 45 exercises (including variations) with instructions and photos. He gives examples of workouts in the back. They are designed to improve functional fitness, flexability and endurance. You may be familiar with some, as he has one-legged squats, one armed push-ups, "supermans", mountain climbers and the like. It is easy to read and follow. Now, I must warn you that some of his stuff, for example "Hindu Squats", may seem controversial. I would go into more detail but I don't know what all he has copywrites on!!
That said, if the above is within your goals, then yes, I feel like you could set up a new or just add into your regular routine. There is no doubt that you would gain strength and flexability if you perform the work correctly. I do not think there is a whole lot of cardio benefit, though.
Now that I have re-visited my book, I think you have spurred me on to add in some of his stuff! Doing this kind of routine consistently would bore me, but added in with Cathe I can see great benefit!
HTH, Julie
