Don't think of it as exercise -- some of us love to work out, some don't. But think like a kid on this subject -- when you were a kid, you didn't exercise, you played. Find something you like to do and do it -- play basketball, or tennis, or soccer, or do martial arts, or yoga -- whatever you really like doing. And in the meantime, keep moving in your daily life -- it's a sedentary life that is bad for you, not avoiding "exercise." Walk to where you're going, bicycle to where you're going, don't sit down all day. If you do that, exercise becomes less necessary.
