I feel that mechanics of technique are of the utmost importance in the arts. Take for example, when one is delivering a reverse punch in karate.If you allow yourself to let your elbow come away from your side,you are throwing it out of alignment,therefore loosing,timing,cordination,speed and power.All body alignment is important in technique and the mechanics thereof,without it you would not be able to achieve the Harmony of motion.
