If cycling is supposed to be so great for our lungs, then why do so many of us still sound like a bunch of wheezing, gasping messes after a hard ride? I mean, shouldnt we be able to breathe like a bunch of Zen masters or something by now? And dont even get me started on the whole cycling strengthens your diaphragm thing - Ive been doing this for years, and I still get winded just walking up a flight of stairs. Is it really just a matter of individual physiology, or is there something more at play here? And while were on the subject, whats up with the whole exercise-induced bronchospasm thing? Ive heard some people claim that its just a fancy way of saying youre not in shape, but that cant be right, can it? I mean, Ive seen plenty of super-fit cyclists who still get hit with it. So whats the deal - is cycling really as good for our lungs as everyone says, or is it just a bunch of hype? And if its not just hype, then why do so many of us still struggle with respiratory issues despite putting in the miles? And another thing - if cycling is so great for our lungs, then why do we still need to worry about air pollution and all that jazz? Shouldnt our lungs be, like, super-resistant to all that stuff by now? And what about the whole cycling at high altitude thing - is that really as beneficial for our lungs as everyone says, or is it just a bunch of nonsense? I mean, Ive heard some people claim that its like a magic bullet for your lungs, but that sounds like a bunch of hooey to me. So whats the real story here - is cycling really the panacea for our lungs that everyone claims it is, or is it just another overhyped fitness fad?
