The Junior Ninjas classes are designed to develop your child’s character. This is where we start really digging in to the depth of Martial Arts and applying the lessons to their lives.

Your child will learn that good character is: doing the right thing when nobody’s looking.

Recommended for ages 9-12, this age group works best in focused 60-minute increments. We give them special combat exercise training so they can make use of all their energy in a positive way, while turning their fitness up to the level of Bruce Lee.

They will also learn their self defense moves to advance to the next rank in a safe, encouraging environment.

This is a fantastic time in a child’s life to have the Martial Arts to lean on as they start to mature and change. Before they become Teens, we want to instill an unshakable confidence so they can handle anything life throws at them.

Students may attend unlimited classes throughout the week. On average, most Junior Ninjas come once or twice a week. Within 6-12 months, you will see a whole new child, ready to take on the world!
