Brazilian Jiu-Jitsu (BJJ) is a martial art that can be beneficial for children in many ways. It can help them develop discipline, control, and physical fitness while having fun with friends 1. BJJ is also considered one of the safest sports for children 2. When introducing kids to BJJ, it’s important to make it fun and entertaining. Mat games such as minnows and sharks, Jiu-Jitsu virus, and others can help kids stay active while practicing control of their bodies 1. BJJ training should focus more on body control and fun rather than intense discipline and competition at younger ages 1. The belt system for kids in BJJ starts at the age of four and continues until they turn fifteen. After they turn fifteen, they will “graduate” to the adult belt system 3. If you’re interested in getting your child involved in BJJ, you should look for a program that prioritizes fun and entertainment while teaching the basics of the discipline 1. Age groups of kids should correlate with the length of classes. 4-7-year-olds should take 30-minute classes, 8-12 should take 45-minute lessons, and under 16s should last about an hour.
