I've heard some athletes have asthma. How do they do it? When I was really young (9-10 years old) the doctors told me I had Asthma, but I think I must've grown out of it or something. Anyways, recently I've had some breathing issues. I've been through all the EKGs, had a CT angiogram, and visited the Pulmonologist, so that means I've been told whatever I may have is not super serious. If I do have some asthma though, it may be more exercise induced. What do athletes do? Exercises to expand or strengthen their lungs? Or something else?
