I am 47, not in bad shape, but feeling the need to do more to keep it that way as the years add up. New to MA, new to this forum. I have started training with a local Karate school here in Bethlehem, PA. Sensei is teaching a style which combines traditional with non traditional to emphasize self defense. Self defense is a good skill to have for me, as I am an airline pilot, and frequently find myself in parts of the world where the rule of law is somewhat lacking. And, it's a great workout. We have started Kata, and my first question is, whether there is a good on-line source to help study and practice Kata at home.....? Thank you, Oscar.
