Of course I only gravitate towards those that do. A thoracic surgeon I know does alot of road rides, a fellow internist bikes 200 miles a week and attends spin classes with me, another anesthesiolgist does pilates and runs, etc. But I would say those who excercise as much as I do comprise twenty percent of the doctors I know. It is hard with our schedules but it is no excuse. It basically means prioritising and getting used to less sleep. (i went on a long moountain bike ride yest evening so had to make up for it with extra work in the wee hours of the morning after i got in some quality play time with daughter and husband).
