Let me know how it goes. I can’t hold my arms over my head for 3 minutes. I have bilateral thoracic outlet syndrome. Any potential benefit for me would be offset by the impact on my neck, back, etc. to those more able bodied… have at it. I sues my martial arts training to control pain but that just involves breathing. Also, there is a negative effect if you do too much. The vavulsa like nature of it would set my head on fire though.
