Since contracting this damn disease I seem to be progressively exercising more and achieving less! (at least that's how it feels) I used to walk at least 5 kms a day but sadly this is in the past and I have settled for 30 minutes on the exercise bike (about 5-6 kms) and about 1-1.5 kms walking on the flat (we live in an area which is predominantly hilly). Currently exploring endobronchial valves which hopefully give me a bit more "breathing space". Strangely I asked my specialist about LVRS or a transplant and he said you are not "ill enough" - I said how ill do I have to be, but this did not elicit a meaningful reply. Ah! Well! back to the exercise bike!
