Acknowlege all instructions with a strong Osu. 14. If you cannot find it in you to show respect to a person who is taking their time to teach you, then you do not belong in a karate dojo. Such obedience develops a bond of trust between the instructor and student, wich improves mutual receptivity, simplifying and speeding the learning process. Always be sure your feet, nails and hands are washed clean for training. In training you often work closely with others.
Nobody likes to train with someone who is dirty.
An accidental blow to a full bladder can be extremely dangerous. Try also to remember that it is not good for the body to train on a full stomach, so avoid eating for at least one hour before class starts.
