Also, there's the fact that exercise is a whole world of deep activities to learn about, think about, and be curious about.  Sports are deep, and to some extent they are intellectual and artistic, just like fatty's precious drawings or whatever.  Even weightlifting is interesting and deep; it encourages and sometimes requires thought about mechanics, physiology, nutrition, medicine, psychology, and so on.  It's not just lifting things and putting them down again.  You have to do that efficiently enough to make progress, and you have to manage your own tendency to want to avoid doing it (supposing you have one), and you have to do it all without hurting yourself too much.  You have to choose which parts of your body to sculpt, what goal to aim for in sculpting them, and what technique to use to achieve that goal.  Like everything, it seems to become more complicated as you look at it more closely,  Like anything, it's as intellectual and creative as you want to make it.  It can easily be less "boring" than some fool's cruddy amateur paintings.
