I'm looking to get back into the martial arts, and I want a different style. I'm looking for a practical defensive style, and since I have certain disabilities, I'm permanently week and have very low endurance for an adult male, so any really physically demanding style is out. Just as important, and this may sounds strange, given all this, but I want a mostly striking art, with maybe like 15 or 20 percent grappling. Also I'd prefer to stick with the more commonly found styles in America. Thanks.
