At IGA kids were are in the process of becoming a Gracie Jiu Jitsu Certified Training Center.  Here is a little about the history of Gracie Jiu-Jitsu.  At a very young age, Helio Gracie learned traditional Japanese Jiu-Jitsu techniques from his older brother, Carlos. In the late 1920s, he began to modify these techniques to accommodate his frail physique with the objective of developing a system that would enable him to defend himself against larger opponents. After years of refinement, he proved his art's effectiveness by routinely defeating larger and stronger opponents, some of whom outweighed him by as much as 100 pounds. As a result, Helio's techniques quickly became the new expression of Jiu-Jitsu in Brazil and set the stage for a worldwide revolution in martial arts.
