Our academy starts training them as young as 3.  Kinder Grapplers is Kindergarten for grapplers.  They are learning how to behave, interact with other kids, stand still, listen, and also grappling.  Teaching them to be comfortable physically engaged with another kid.  They learn how to respect their coach, stand still, etc.  After that they graduate into our Junior 1 program, 6 to 9 years old.  They are learning Gracie Jiu-Jitsu techniques.  Juniors 2 are 10 years old and up and they are learning the same things as the adult Jiu-Jitsu classes.
