The recommendation for those of us with COPD, like everyone else, is 30 minutes of aerobic activity every day. Walking is usually what's recommended; we all have to do it. Doesn't matter how far you go or whether you go anywhere. You can march in place if that's your choice. And pace isn't an issue either. Generally it's best if you walk at a reasonable place you can maintain for 30 minutes without stopping for breath after you work your way up to it.

Walking is the best thing for you, even if you only take a few steps. I try to walk on my back patio with my walker.

Yes walking. It was difficult at first, I could only walk like 10 minutes but I kept at it and I walked 6000 steps the other day. It took me quite a while but I just keep pushing on with many breaks.

My Dr. told me to walk more and loose some weight. Exercise is the best think you can do to help with this.
