After nearly a century of testing in a wide variety of settings, Grand Master Helio Gracie’s system of self-defense remains fundamentally sound and intact. To be sure, three generations of Gracie family members and other equally committed practitioners of the art have evolved the original techniques and added to the Gracie Jiu-Jitsu arsenal. All of these changes, however, strictly adhere to the Grand Master’s requirements for street applicability, energy efficiency, and natural body movement. Today, we call these requirements the “Gracie Guidelines.”
On your path towards Gracie Jiu-Jitsu mastery, your knowledge of the Gracie Guidelines will serve you in two important ways. First, it will enable you to solve problems on your own by modifying techniques in accordance with the guidelines, and second, it will enable you to recognize the multitude of impure techniques that are being developed by instructors who do not know, or choose not to adhere to the founding principles of the art.
