Eli5 How do lungs get stronger?

763 views

So I’m a runner and one of the road blocks that pops up from time to time is that my legs feel fine, but my lungs just can’t keep up with the speed. I’ve noticed after a hard run, I get a sort of cough and a bit of mucous build up like I’ve damaged my lungs in a way. Is this the same process as other muscles? Create little micro tears in muscle, body sends nutrients to site of damage, tears recover, muscle gets bigger and stronger. Or is there something else at play that makes our lungs stronger over time?

mann i have the same feeling after a run too. My legs and muscles are generally fine but its my lungs that just cant take it. Sometimes after an intense workout I get this cold feeling in my lungs, which is kind of similar to the feeling you get after you brush. Hoping someone has answers here
