Deep breathing sustains your energy level on the trail
I'm not sure when it happened. All I know is when it did, it changed my days on the trail forever. It has nothing to do with the latest ultralight gear discovery or fitness app. It's about something that's with you 24-7. Your lungs. I'm talking about deep breathing.
Like many people, when I first started hiking, I frequently needed to stop to catch my breath, most often on steep ascents. I'd lean on a tree, wait for my breathing to slow down, then I'd start in again. I didn't think there was anything wrong with this. I thought it was a normal part of doing aerobic exercise with a bit of the need to get into better shape thrown into the mix.
I was only partially right.
