"Having competed in National & International IronMan and Ultra Marathons, I had worked with many different coaches, yet no one ever taught me how important is breathing for improving my performance and conditioning. Although skeptical at first, I read the science behind Buteyko Breathing and have seen immediate changes in mental stamina and focus. I didn't even know the importance of nasal breathing and the dangers of mouth breathing until I met Sahand and worked with him to keep enahncing my performance. I now have specific tools to keep improving my VO2 max and recovery time as well as increasing my sleep score which are the most important goals of mine"
