I was originally drawn to this book after being told it was a useful guide for all movement therapists and as an injured athlete with a medical system that had consistently failed me, I needed a solution.
I kept reading the book and implementing what I had learned into my own training, improving my mobility and...
And?
Unfortunately not much. Although it may provide some useful insights into how certain shortened muscles can affect the entire system and change our posture, the method is simply not supported by research. "Fascial release" which is literally core to this book is not supported by research, despite a considerable amount of research being done on it. Fascial release works for short term benefits such as improving mobility and reduced pain... but that's about it.
The anatomical lines drawn within this book have similarly faced scrutiny. It creates lines or "trains" by connecting train tracks with a hint of guesswork and imagination. The drawings are well made and make the book digestible, but unfortunately this book is not what it is marketed to be. It's not evidence based, it's entirely centered around somewhat pointless fascial release methods, and is honestly, to an extent, pseudoscientific. Unlike Tomas Myers, I'm no expert of the field, although I have formulated this criticism surrounding the book through the perspective of evidence-based experts on the field who've given genuine evidence opposing fascial release.
And maybe I'm missing the "bigger picture" or the actual purpose of the book (although movement therapists have been the one to deter me from this book), but there's no show of meta-discussion involving the techniques and anatomy within the book, leading me to conclude that this book has pseudoscientific elements to it and was unfortunately a waste of time.
If you're genuinely interested though, I do recommend reading it if you want to understand the anatomical framework provided in this book, as the book does a good job of communicating it extensively. Just don't expect the methods to work longterm.
