Pressing or striking points may also serve to shift an opponent's body position, manipulating it into a more favorable position for a strike or a throw. Many throwing techniques secure the opponent's base and then push, pull, or lift the trunk to unbalance for the throw. When applied properly, the opponent is now carrying your weight as well as his own. Most people can not maneuver efficiently if they suddenly weigh as much as two people. This technique momentarily contains and immobilizes the opponent, creating many opportunities.
Extremities are themselves targets, and vulnerable to being struck, locked, twisted, and fractured.
This allows you to shorten the range while controlling and manipulating the opponent in such a way that the risk of being struck on the way in is minimized. If done properly these techniques allow you to control the opponent's center and balance sufficiently that even if you are struck, the strike's power is greatly neutralized, because the opponent cannot rotate his center to generate power. Of course these techniques may lead into locks, joint breaks, or throws themselves or set up a strike. As can be seen from the above discussion, the trunk and extremities are used in basically two ways. One, as targets themselves which may be damaged or struck, or two, as tools for manipulating the opponents balance.
