The Buteyko Method of breathing is revolutionary in many ways primarily because 99% of us don't breathe properly the way were meant to breathe. For me, it was an eye-opening experience that is confirmed with practice and results which continues today.
It is a lifestyle...this way of breathing...but it can only be taught and learned with practice and the results are remarkable. The practices eventually transform into good habits and the benefits that come from it are well worth the effort.
Thomas is a great teacher and motivator...you need both when starting out. I highly recommend Buteyko Center USA by Skype or in person...you will be glad you did.
