It is important to integrate a lowered center of gravity into your training regimen as it is one of the most common reactions to being scared and/or startled. The reason for this survival reaction is that it prepares us to move. In fact, if we try to integrate lateral movement into our presentation quickly when we are training, but do not integrate lowering our center of gravity first, we will find that we cannot move as far or as fast. In fact, we cannot move effectively at all if we do not lower our center of gravity first.
When training be sure to lower your center of gravity before you initiate your draw stroke (or any other learned motion) so that you are congruent with actions in a real event. During a dynamic critical incident your body will lower its center of gravity instinctively, before or as you process the stimuli that will initiate any learned response.
