Brazilian Jiu Jitsu(BJJ) is a grappling martial art wth applications in self defense. It is strikeless(no punches, kicks, etc.)ground based fighting with partial emphasis on takedowns. In place of strikes, there are submissions.
Submissions are chokes or joint locks that cause your opponent/training partner to "tap" out. A tap is a withdrawal from a fight. It is normally done with a series of hits in quick succession that notify your opponent to immediately stop their submission.
Some of the key concepts in Jiu Jitsu are efficiency and positional dominance. Both of these enable a smaller, weaker person to be able to submit a larger, stronger opponent.
In addition to the self defense side, Brazilian Jiu Jitsu is often practiced as a sport, both on its own and in conjunction with other forms of martial arts. There are numerous Jiu Jitsu tournaments held each year in Indiana alone.
BJJ is an incredible martial art to practice, not only due its effectiveness, but because of the many positive effects that roll into everyday life. It is great exercise, helps you sleep better, gives you confidence, brings you a into a close community with plenty of great people, gives you new outlooks on life, and of course, teaches you how to defend yourself. We at IUBJJ highly recommend you try it for yourself!
