The Dojang is foremost a place of education. A place where you come to learn mental as well as physical lessons. I am an educator, not a drill instructor. My purpose to help you learn, to give you the tools and experience to become self sufficient. I am here to help you find what you're looking for, even if it turns out to be something other than what you initially sought.
Training consists of many components.
During any given class I may lecture for 10 to 15 minutes, have you practice basic movements, forms, and then teach you something completely new. During a one-hour class you should gain both physical and mental knowledge. For a white belt student, class is usually a large increase in their level of physical activity, however, for students who have trained for at least a couple of years this type of workout should require very little physical effort. I have stated before that martial art training may start as physical activity but after a period the emphasis should move to mental training. Therefore, your training in the Dojang should not be focused so much on the physical, you should be trying to develop your mental understanding as well.
