What would you recommend for starting a daily exercise/weight training and physical therapy program to someone who is in relatively good shape but has neglected doing these things for several years? I am a 29-year-old male and would like to see a greater improvement in my PFT scores. I am on Pulmozyme and TOBI every other month and this has caused some improvement. I used to work out with weights and it helped tremendously but I didn't keep it up unfortunately. Also, how important is it to have physical therapy or use an air clearing device of some kind? I've never felt that chest percussion or any of those things did much for me at all. However, my PFT's have been going down for the past couple of years and I really want to get them back up. I have not had IV's or an active infection for many years but it seems my lungs are becoming obstructed anyway, based on my test results. Thanks for your help.
