I go to rehab also. When I first started I could barely do anything. This was about 5 weeks ago. Now I'm walking 2 miles and riding the bike 3 miles. It does work helping you stronger and making breathing easier. Ask your Dr about going, best thing I've done for myself.

I started in pulmonary rehab at the hospital I could only walk 200 ft in 6 min and that was stopping to catch my breath. 9 weeks later I did 550 feet in 6 minutes so I would say to you" exercise does the body good." intake breathing thru your nose and exhale thru your mouth like you're whistling. That helps. Don't push yourself to the point of exhaustion though with any exercise. It takes time to build up strength and stamina. I still go to rehab at least 3 times a week because you do feel better afterward. Whatever you choose I wish you better breathing, God Bless

Thanx 's I hope some day I will be able to get to rehab by. My self

Walking and doing breathing techniques at same time effective

Yes, rehab . . but you have to put some work into it . . will increase your lung function . . Socially mix with people with respiratory issues and help you general health. I've been going near 5 years now. Stationary bike or treadmill help. Walking at your pace with a friend is the best for me plus rehab most the other days.
