 [ Symptoms ] i recently quit smoking how can i get back into exercising any suggestions to help get my lungs back into shape [ Disease ] lungs are not muscle so there is nothing specific you can do to train them like you might your legs but aerobic activity will get them back into what they do best which is process oxygen and send it to your heart and after just a year of smoking you will get it back i suggest you just go slowly and work within your capability keep in mind that it is not just the lungs you are fighting but deconditioning too even if you had not been smoking you would still be struggling since it is been a year with no activity do not expect to get right back into where you were fitness wise when you stopped particularly if you were very fit but you will notice effects in just a few weeks if you pace yourself and within a few months your fitness will improve substantially so give it 12 16 weeks to notice real differences and then you can take it from there good job on quitting smoking it is the most dangerous health risk there is
