Great - this sounds like a powerful experience. We use breathwork as part of a retreat I run. However, it isn't a 2.5 hour experience like this.

It's quite a long time! My feeling is that it could probably be condensed to 1.5 hours if the breathers were able to breathe very strongly at the beginning.
