As an athlete this Pranayama course (as well as the same practice during the TT in Goa and Bali) is like strength training for the respiratory system , like getting the breathing system to a good gym and do weight lifting , gradually , sustainable and therefore functional. Also, I adopted it as altitude training before a run race in the Himalayas and the results were better than doing actual altitude adaptation! Real strength is also mobility and this course allows you to train both : strength in slowing down and holding , as well as flexibility, mobility of the diaphragm and the 12 bridges, allowing to move in strength without tensing. Plus it’s easy progression to remember and therefore sustainable for daily practice.
