Your thoughts on the McGuire program?

Your thoughts on the McGuire program? So I just watched [this](https://www.youtube.com/watch?v=tvs6gcSlMMc) and I wanted to know if it really works? I'm really interested in this since I haven't really been focusing on the physical part of my recovery. I've been doing lots of meditation and affirmations, but not like breathing excercises. If here's someone who has experience with this please respond, I'm not sure if this is worth doing.
