Being active is great and it keeps you from being socially isolated, but being active is different from having a regular, daily, consistent and aggressive exercise program. You do the exercise program every day because that's what allows you to be active.

If you're not exercising, your ability to be active will diminish on a regular basis and you'll have significant problems over time.

When I am having a flare up though, I don't have the strength to engage in real exercise. Maybe it is age related too since I am in my 79th year now. Don't know. Riding the stationery bike for a half hour seems to work best for me when I am able to do so.

Yes , I was on # 2 for 24/7 for 3 mo. then only on # 2 when active , more then walking. Have you been to COPD rehab. ,if not GO , they teach you how to breath right.
