After having an enforced week off from running. I started back today but went on the treadmill at the gym to make sure things are healed. I found myself a lot more relaxed and started to actively work on my breathing. I always breathe through my mouth. In and out. Someone once told me it's better to take breaths In through your nose and out through your mouth. I tried this and just ended up totally out of breath. It's like I can't get enough air through my nose. Does anyone find it easy breathing that way?
