A clear example of book that should have been an article. There’s some good stuff in here on breath work and its (arguable) importance to health as well as heaping helpings of the kind of anecdotal bro science I tend to enjoy, but don’t take too seriously. All in all, the chaff outweighs the wheat, in my opinion. Still of interest to those intrigued by breath work with excellent easy to follow instructions on various kinds of breath work.
