Hi everyone
hope this helps someone. i attended the pulmonary rehab class near me in february and couldn't walk very far at all.(40% lung function).Kept up the exercises at home as and when i felt like it and have recently completed the St Barnabas "one night in a onsie" 10k walk,including a hill.i certainly wasn't the fastest but the sense of achievement is totally amazing.
So dont give up...little and often and only when you can..does really help
