Right, it isn't just that exercise is good for you but rather all the time spent not exercising is bad for you.
(That being said, I wonder if the extreme types of workout many people promote is actually good, or if it does more damage than good in the long run. I guess some people believe that one extreme can out-weight another extreme.)
