Student safety is a primary concern during all classes. The completion of the Fundamentals curriculum reduces the possibility of injury to a minimal level. The practice of GJJ at our centre is safe and sound. Grand Master Helio Gracie’s teaching methods constantly emphasize the importance of keeping students out of harm’s way. Accidents may happen, however, lack of seriousness during training and the resultant careless application of technique or counter-technique contribute greatly to injury. Careless practice is disrespectful to the spirit of Traditional Gracie Jiu-Jitsu.
