Exercise -- especially exercise that works your lungs and heart -- has many benefits for those with chronic obstructive pulmonary disease (COPD). Exercise can:
Improve how well your body uses oxygen. That’s important because people with COPD use more energy to breathe than other people do.
Decrease your symptoms and improve your breathing
Strengthen your heart, lower your blood pressure, and improve your circulation
Improve your energy, making it possible to stay more active
