A stance is the starting point of every taekwondo movement.
The forceful and finer techniques of attack and defence are largely denendent on a correct stance.Stability, agility, balance and flexibility are the controlling factors. Basic principles for the proper stance are:
Keep the back straight with few exceptions.
Relax the shoulders.
Tense the abdomen.
Maintain a correct facing. The stance may be full facing, half facing or side facing the opponent.
