Hi Cheryl, I keep it varied because to be quite honest I hate to exercise but when my best friend, who is a doctor, told me I had to exercise everyday (she said this to me on the day I was diagnosed with bronchiectasis) to keep my lungs working I did what I was I told... 🙂 So I decided that I had to make it like brushing my teeth or eating. I HAD to do it no matter what. So on mornings when I really don't want to get up and get dressed and go to the gym or go walking I MAKE myself get up and do it. So I joined a gym (even though you could just walk regularly) and I take anywhere from 3-4 aerobics classes a week ( some with weights) for 45 minutes each time. It's about 40 minutes of work. On the other days I do a two mile power walk or walk very briskly for 30-40 minutes and that's a little over two miles for me. And then if it's raining or cold or I don't want to go anywhere I get on You Tube and find an aerobics class that I like. And then on days when I don't want to do any of that I just turn on my exercise music on and dance in my house. I always wear a Fitbit so I know what kind of workout I'm getting. I also look at this in a psychological way in that I feel like I'm telling my lungs that I'm in charge and I'm keeping those damn bugs out of there and trying to make it as inhospitable as I can for them. I don't want them setting up shop in my lungs. So I've been doing this for four years (diagnosed six years ago) and I've been in remission for four years. And I also do other stuff like take liposomal glutathione which is the single most important antioxidant in the human body (says my functional medicine doctor). As we age our glutathione levels drop so I just want to keep the levels up. I also take some herbs and other supplements that are supposedly good for the lungs and good for you in general. In a nutshell I just try and do everything I can to make my lung environment healthy. And of course, nebbing with saline solution! Hope that answers your question! Nan
