Because of the faster exhale & inhale I found that the rate at which I was breathing was the same even after holding each breath just a little. I have no idea if this technique has any scientific validity whatsoever, but I read an article the other day about how your lungs exchange gasses during each breath and so I'm sort of trying to give the lungs a chance to get the air in deeper and once in there a chance to do its gas exchange thing more thoroughly, if that makes any sense.

So, what is a good training technique to improve your aerobic capacity? I'd love to have more lungpower to get more out of the legs.....
