What is Kung Fu San Soo? Kung Fu San Soo is considered, by many, to be the most sophisticated and complete form of martial arts in existence today. Inside Kung Fu Magazine refers to San Soo as "Legendary" and "Devastating". Both of these statements could be considered opinion and many consider them fact, but all agree that Kung Fu San Soo is not a sport. By it's very definition; the complete use of a man in hand to hand combat, the art cannot conform to the specifications of being a sport. In order for it to be a sport, it must be governed by a set of rules. However, if a set of rules were applied to San Soo, a fighter's techniques would be limited and they would no longer be executing Kung Fu San Soo.

San Soo is a martial art, which incorporates principles of leverage and movement, as well as proper breathing and concentration to create a powerful and effective fighter. Many of the leverage moves can find their basis in the principles of physics. Although Lo Si Fu never studied physics, he did understand the mechanics of how a body moves, acts and reacts in a given situation. He understood principles of motion that many go to school for years to learn, but his education came through experience.

There are two keys to the success of a San Soo fighter. First, there is the versatility of the movements. The combinations of blocks, punches, kicks, throws and leverage moves can be altered instantly to respond to any situation a fighter may encounter. Offense is the second key. A San Soo fighter does not fight defensively. Once it has been determined that a confrontation cannot be avoided, the San Soo fighter reacts offensively, taking their opponent by surprise to end the fight quickly. In Lo Si Fu's own words, "You can't win a fight by defensive, offense to win."

In addition to the fighting techniques learned in San Soo, the student learns agility, balance, coordination, humility and respect for human life. While learning the techniques and movements of San Soo are very important, Lo Si Fu always emphasized the importance of humility. According to him, "The art of Kung Fu San Soo lies not in victory or defeat, but in teaching and building human character."
