Is There a Scientific Reason Why We May Want to Train Our Respiratory Muscles?

The reason why we may want to focus specifically on breathing is that it's very hard to kind of do normally riht. You're really trying to target the respiratory muscles by themselves and have them kind of train them separately, without kind of forcing the legs and arms and other parts of your body to do a lot of work. And if we can train those muscles specifically to become stronger and more efficient in oxygen use, than that is less oxygen that they are requiring. So that's really this idea of whether its different respiratory kind of training systems that we may see, is really to focus on the actual respiratory muscles.
