I used to practice KravMaga and systema as a full contact martial art for more then 10 years, both are practical martial arts, if you do not mind getting black and blue from time to time, it will also improve your physical fitness, conditioning, and instincts very fast. For the last several years i am practicing Iaido, which is generally speaking, the martial art of drawing, striking, shaking off the blood, and sheathing back the sword. It has no practical use as a martial method,and is highly ceremonial. I find it to be the most demanding martial art i ever practiced in terms of mental requirements. The simplest forms take years to master, it is a humbling and often frustrating experience, I highly recommend.
