Thanks for the great feedback! I am also a fan of both EMDR and Yoga. EMDR has a good reputation with other combat vets I know of who've tried it, and Yoga is certainly a great outlet for the reasons you list. I also agree that finding what works for yourself as an individual is the way to go in general, and even wrote a chapter about that in the book mentioned in this video.
My first option in the polling responses was cut off, so you can't read the rest of what it listed as the benefits of training Muay Thai or other martial arts. Like Yoga and other exercise-oriented activities, training a martial art does precisely as you say - from improving balance to strength, flexibility, and does have a significant impact on both physical as well as psychological health. Where I think martial arts training may even have another bonus effect that maybe other activities don't so much, is in the self-confidence usually boosted in the practitioner - and I believe that can be a healing force that helps set martial arts training apart in helping a trauma survivor.
Thanks again so much for your thoughtful comment, and I wish you all the best in your path of recovery as well.
