If you just want fitness/exercise, might I recommend parkour? Most people don't consider it a martial art, but they do consider it a discipline rather than a sport. It requires the same level of dedication and practice to be good at, and enhances your world view in a similar way to martial arts. The real benefit, I find, is that it is far more social than martial arts; there's a great community of traceurs around the world who are constantly trying new things and helping each other out. I'm not going to go into much more detail unless you're interested, so reply here if you are.
