BUGI has methodology, rules and principles. Application of these physical principles allows one to more effectively utilize any technique. Their effectiveness is determined by whether they are applied at the right time, in the right way and with the right amount of energy. For example, BUGI includes the elements of speed and power. Power is the emergence of energy which is used to achieve a goal.
Speed can create power and power can substitute for the lack of speed.
Speed can create real destructive power, for example, when a hurricane wind blows a straw to such a velocity that it penetrates a wall. Conversely, even if moving slowly, a power of sufficient force can push through the same wall. Effectiveness depends on whether they are applied correctly in light of particular conditions. The first requirement for an accurate technique is proper posture. Proper posture allows one to generate all the power that one possesses, execute movements accurately and rapidly, and also maximize one's attacking or defensive power.
