It seems that I have an easier time breathing in the last week or two. I can't explain it, but I feel like I can take fuller breaths. My body seems to want to take fuller breaths, and it is effortless. Could this be from the low hr training? Can't say. I am not sure if I am just imagining this as well.
Breathing, ironically, is something I know a lot about and am good at. I spent most of my youth and college days playing the.... you guessed it.... Tuba. I was actually a performance major for 2 years with the tuba. Getting a lot of air, quickly, in a relaxed manner was something I practiced for years. My professor, Rex Martin, was an under study to the late Arnold Jacobs, probably the best wind teacher of our time. Breathing was a big deal in the studio.
So, early on, I learned how to maximize breathing without thinking about it. I was even blessed with a 6 liter lung capacity. I am probably the only person you will ever meet who has had their lung capacity tested. In reality, contrary to conventional thinking, lung capacity does not have much to do with how well you play the tuba. (or any instrument for that manner). I am not sure it makes that big of a difference for running, either, if you don't have an efficient manner of getting that oxygen into your blood.
So, I digress.
In the Maffetone book he talks about stressing your body by overtraining through the adrenal glands. I am sure there is a link here with easier breathing, but I don't know. I mean, it was easy to breath before this. It is just "easier"
Just watch, I will get sick tomorrow.
