Positions. Timing. Leverage!
Brazilian Ju-jitsu is a grappling martial art that employs position, transitions, timing, leverage, and technique to subdue an opponent. While the sport of Brazilian Ju-jitsu has exploded in the United States (tournaments abound, and this avenue is available if desired), the applicability of Brazilian Jiu-jitsu in the realm of self defense is real. When studies say that a majority of fights end up on the ground, common sense tells us that learning what to do while there would be beneficial.
Part of the beauty of ju jitsu is the ability to train against 100% resistance and test the techniques for practical success. GMA's curriculum for ju jitsu is to find the moves and positions that work for an individual and work on mastering them while spending little time on moves that have low percentages of success. The result is a dedication to fundamental positions, transitions, and submission.
Classes are a structured differently than our more traditional arts (Kenpo Karate) because of the importance on drilling against live resistance. While the classes are structured more informally than the traditional arts, the practice of ju jitsu requires, discipline, attention, and maturity.
