A lot of good has been said about this book by previous reviewers, so I'll only agree with those glowing remarks and add one warning to owners of other Body Control Pilates books -- this book just cuts and pastes entire paragraphs and pages of info from the first book "Body Control" and "The Pilates Prescription for Back Pain" (which is just another title for the "Body Control Back Book").
Basically, Body Control are putting out the same (really great!) book with only a few updates and changes here and there (newer studies on engaging the pelvic floor before scooping & hollowing has replaced the old navel-to-spine only advice, for instance) -- and a lot better photographs and graphics.
So, if you own several other Body Control books, like I do, and aren't interested in fancy photography, you'll be disappointed here. But if you are new to their range of books and this is to be your first or only one -- go for it, you cannot do better, this Method is fantastic.
