SWIM!
PFTs above 100%. FEV1/FVC ratio is slightly low. Culture PA. Take enzymes. 4 polypectomies, no sense of smell. PFTs dropped during college when I did little exercise and no physiotherapy. Since then I've exercised regularly (but no physio) and PFTs have remained stable.
The best exercise, hands down, for my lungs is swimming. 1.5 hours of pretty vigorous (albeit slow) swimming for 6 months boosted my pfts by 10 points, after having been stable for about 5 years. If you want to boost your lung capacity, swim. Having said that, I should probably get back in the pool.
Quick search found: (of course maybe people with large lungs are better at swimming to begin with, but hey)
