Pressure points are one of the most widely misunderstood concepts in martial arts. Many different legends have been repeated over the years regarding secretive and lethal techniques. There is nothing mystical or magical about the existence of pressure points or their application in self-defense.
Pressure points are nerve clusters, frequently around major muscle groups, that when struck or grabbed can cause the nearby muscle groups to spasm in a painful manner. While there are many different ways of getting to them in a self-defense situation, there are a few steps to make it easier to find them when you need to.
