ALL OF OUR KIDS PROGRAMS ARE BULLY-PROOF Kid’s classes are for children ages 5-12. Teenagers generally attend adult classes, such as our Beginner BJJ class. In addition to staying active and involved in a sport, BJJ promotes respect and discipline and builds up confidence and self-esteem in kids. We have been told many times how our kids’ confidence has prevented or stopped bullying or improved behavior in school. While no martial art or activity can guarantee an improvement in school, or bullying, or general behavior, BJJ has helped many of our students.
