I’m not qualified to judge the plausibility/truth of the thesis, and I only spent about a week with the book, not nearly enough time to really do all the exercises. I did learn some things, and definitely want to investigate this approach further. Greene has a good writing voice, and the book is generally clear and readable.

All that said: it would benefit from an index; the layout is very poor (for example, step 4 of a short 4-step exercise should not be on the next page); the diagrams are ok but insufficient—not everything referenced is clearly labeled, and it would be very helpful to see diagrams of the exercises in action, in addition to the included anatomy cutaways. (Would also love to see videos of people doing the exercises; maybe they’re out there.) And, while the writing is good, it seems overly specific and some areas and overly generalized in others—like Greene knows what he’s talking about but doesn’t get it all down on the page.

I guess I see a lot of room for an updated and improved edition, assuming anyone still believes in this basic pedagogy.
