There's stretching and there's extreme stretching.
I'm a great believer in stretches. I don't find it increases my energy (I wish) but it IS vital for pain relief, balance, relaxation, and maintaining (or increasing) range of motion and mobility. Possibly because it's seen as boring, stretching is an overlooked form of exercise. I was also impressed with the author's claim that stretching WITH RESISTANCE increases the effectiveness of the stretch. This makes sense and I will incorporate this into my daily routine.
I tried all of these and was able to do most of them. The "fold" is a concept that was introduced to me by my-sister-the-yoga-freak and it has been of great benefit. The author shows several variations. The explanations are simple and easy-to-follow. The pictures would be much more effective if shot in a studio with a plain background and the models wearing contrasting clothing. I found some of the pictures quite confusing.
The only other caveat I have to offer is that some of these stretches are rather extreme. I got a bit carried away with the "Gorilla Stretch" and fell on my face. (Damn, that would have made a GREAT video review.) If you're older, overweight, out of shape, or have physical disabilities, modify the stretch and do what you can do without injuring yourself. Yes, "Treading the Needle" is a good stretch for sciatica sufferers, but even lying on your back with your knees bent is helpful. Take it slowly. You don't have to do it just like those slim, young models in order to get real benefits.
I agree with the author about the importance of breath control during stretching. As she says, yoga instruction is helpful in that regard. Tai chi is a wonderful form of exercise that promotes balance, flexibility, and breath control. Scott Cole's DVDs are inexpensive and easy-to-follow. If you want to try some simple yoga poses, I can recommend YOGA, THE BACK PAIN CURE by Howard Van Es. It has been very helpful to me.
As Ms. Schoen says, you don't have any excuse to avoid stretching. It can be done in your own home while you watch TV. Better yet, turn the set off and enjoy some relaxing music while you stretch. You'll feel better.
