I'm looking at starting a martial art training. I did Karate as a young teenager, and I enjoyed it (made it to brown belt even, though I wasn't that good looking back! ). Now - well I'm looking for a self-defence-oriented form. I'm also looking for something that is reasonably aligned with modern fitness principles. I'm a keen fitness devotee in many ways, and I won't be interested in doing something that forces me to do moves / training that I find completely bad physiologically. I am currently considering the following, primarily as I've found a local place that runs these forms. That said, if I searched, I'm sure I'd find most forms locally. Brazilian Jiu Jitsu Hapkido Tae Kwon Do Any suggestions (keeping in mind my defence and fitness-aligned goals)?
