Found this on the American Council on Exercise Forum:
Sounds paradoxical but still there are plenty of weekend warriors and athletes alike that work out routinely and still smoke 4-5 cigarettes a day. I am writing an article about this phenomenon for the New York Times so if you know any smokers who exercise, or if you are a trainer who has helped a client quit smoking, I am looking for some additional interview subjects. Email me email@example.com.
