I trained in Eskrima (~aka Kali or Arnis) for several years and loved it. It's a Filipino art most commonly recognized as stick fighting or knife fighting, but is a complete system of hand-to-hand combat. After having sticks flying at you for awhile, suddenly hands aren't nearly as threatening. To get the most out of it, do expect to get a little bruised and sore. The bruising stops as you learn the relaxation aspects of the art, though you still get a good sore.
Most schools do not train eskrima as aerobic exercise, as might be typical of other arts, but generally are strictly technique and drill oriented. If you're looking to lose a lot of weight through martial arts training, another art might be better suited. But if you want to learn basic, effective techniques for self-defense and can handle the exercise and fitness aspects on your own, then I highly recommend looking for a good school near you. Doce Pares is a very well-respected organization that I can't say enough good things about.
