a little while back someone told me something about some type of breathing, I think associated with a certain yoga style, through which some guy has increased his lung capacity to three times what is average. For some reason I wasn't paying much attention at the time.I know capacity isn't really a problem with cf, but I also think it may help in some ways. I was wondering if anyone else knows anything about this; what style of yoga it is associated with, or if it's something completely different, and anything at all about it together with cf.,
