When trying to control your breathing after a workout... if there is tightness in your upper chest area, is it better to force
yourself to take extremely deep breaths or to hit the point of where it's just slightly uncomfortable and stop. I'm in extremely bad shape and just starting to get back into cardio. If I take the deep deep breaths it hits the point of almost wanting to cough... but it makes me think that I'm expanding my lung capacity. Which is better?
