Brazilian Jiu-Jitsu (BJJ) “Randori” or free sparring against a live, resisting opponent.
One of the things that separate Brazilian Jiu-Jitsu from other martial arts is that sparring is considered essential to a student’s progression. Students test their skills and develop them under realistic conditions, with minimal risk of injury.
This is a “live” martial art where practitioners can go 100% in training without fear of injuring their opponent. This constant training against live, fully resisting opponents sets BJJ apart from other traditional martial arts. Brazilian Jiu-Jitsu’s emphasis on joint locks and maneuvering rather than strikes means that technique can be practiced at full speed and near full power, similar to the effort and technique used in a real fight.
Training partners resist and counter just as they would in an actual fight, providing real-world experience. This practice of live training, officially called Randori but commonly known as “rolling” in BJJ circles, is considered by many BJJ practitioners to be the major factor differentiating combat sports.
