@zippy222 That is really good and encouraging to hear how the exercise is going for you. It's unfortunate that so many people with various lung diseases bail out after the first minute of exercising because they get tired or their lungs seem to struggle. I hope your message will encourage more people to stick with their exercises, no matter how trivial those exercises might seem. Many, many studies have shown the benefits, both physical and in terms of mental health that come from regular exercise. Cheers to you.
