The Day 6 exercise was a bit challenging in two ways. First it was a busy morning with work issues which made it hard to truly relax so breath holds were on the shorter side. Second was that the "exhaled" state seemed to get uncomfortable very quickly. I believe in the exhaled or neutral diaphragm breath hold you are experiencing O2 saturation decline as the trigger to breath more than rising CO2 levels. With my lungs full I was able to do a 1:45 breath hold and for a neutral diaphragm I was only able to reach 1:03. Perhaps more practice with both of these types of breath holds will lead to better future times.

Just finished Day 7. Great mini course. Thanks Stig. Well done. Made it to 3:30. Excited to continue to the journey.
