A a jam-packed week of fun, confidence building, and character development! Unshakable Confidence with Gracie Jiu-Jitsu At the foundation of the Gracie Bullyproof program is the belief that a confident child is a "bullyproof" child. By giving children the non-violent self-defense skills to neutralize the violent physical attack of an aggressive bully, we give them the unshakable confidence needed to verbally address bullies and defeat them WITHOUT violence. The Gracie Bullyproof Summer Camp is specifically designed for kids between the ages of 6 and 13.
