I haven't gotten his stretching stuff, but enjoy his kettlebell stuff and general strength writing. His assertion that strength is itself a skill that can be mastered like any other, not just the result of having mass and using sheer muscular exertion, is attractive to me and his tension techniques in that regard seem fruitful and correct. His work contains plenty of hype and always seems to cost a fortune, but actually has enough substance to reward repeated readings and bear up well under repeated scrutiny.
I've found "The Naked Warrior," a book that concentrates on two bodyweight exercises(a one-legged balance squat called the "pistol" and the one-armed push-up) and on strength generation principles, especially helpful, and "Power to the People" kind of works with it in tandem.
I have been hesitant to buy Pavel's stretching work because it is so high priced and the multiple DVD's are so short. I do feel they could be compressed together into one DVD and still sold at the same price.
