I think if you can run, you don't need purse lip breathing. It's for people with COPD who get short of breath while just walking and couldn't run if their life depended on it!

Good grief if you can run you probably don't have very serious COPD....I struggle with walking....turtle speed is my fast forward. :)+

Took me two years to get to this point. I didn't think I could run either. I started just walking.

I can run fine without pursed lip breathing.

I don't think pursed lip breathing is the problem; I think probably running is.
