So, I've been to a few dojos in my area, and Ive noticed that a lot of the instructors are extremely overweight. When they demonstrate techniques they look really bad and, horribly unbalanced; however, some of them seem to have a lot of martial arts experience/knowledge. Many of them have actually lived and trained in Japan! I've seen photos of these instructors when they were younger, and I would have loved to train with them then, but now that they have let themselves go I'm sort of wary. So, what do you guys think? Can an overweight instructor teach you to be a good martial artist or will the fact that they can no longer walk the walk effect the training youre receiving?
