Being in a good shape it's sometimes for me hard to breathe (I need to breath more and deeper) after doing barbell squats, especially after long omissions. Almost none of other exercises make me feel so breathless.
I'm thinking that this is because of a large weight of muscles in legs and totally not enough blood to serve.
What exercises can be added to train, maybe, lungs?
UPD: I have no cardio problems so. And yes, I will consult with my physician as soon as I can. I think the answer I will receive would be useful.
