No one should struggle with lack of progress.

We know how frustrating it is to do your best with clients, only to see a lack of progress in their results. To make matters worse, there are times when there are limitations placed on both training time and equipment. 

That is why Karsten created the science-based yet practical, A Course In Breathing workshop. 

That is why he teaches A Course In Breathing worldwide every year.

One seminar in particular that I really enjoyed was 'A Course in Breathing.' My favorite technique was the French Press Diaphragmatic Breathing Technique. This technique alone has helped my clients increase their core strength and lifts. I have 2 partial hernias that have not gotten any worse and in fact have healed,due to being taught this technique. Clients of mine that have suffered herniashave also had great success in lifting and core training due to this technique.With the education offered in this seminar, I have had clients do hands-on testson themselves by placing fingers in specific areasof their core which allows them to feel the techniques working.
