Hi everyone. I'm currently in a pulmonary rehab class and my pulmo therapist has a harmonica class that she says improves your muscles surrounding your lungs making your lungs feel clearer. I'v went to a couple of classes with it and you can really feel a difference a while. Anywho I wanted to know if anyone else does musical instruments or activity that helps with lung improvement and what it's done or not done for you. Thanks. <img src="i/expressions/nebulizer.gif" border="0">
