Forte Ninjas is a program for kids (and adults!) at least 4 years of age. In our classes, they will learn about obstacle course racing, receive instruction on proper technique, participate in cardiovascular and strength-building activities, and have plenty of time to enjoy our ever-growing array of obstacles. Ninja classes are not only FUN, they aid in building self-esteem, confidence, and a sense of accomplishment. Our structured classes help children improve their self-control and experience the importance of discipline.


Forte’s Ninja Team is an invite-only competitive program for kids ages 6-17. This group competes both on the regional level with NENA (New England Ninja Association), and the national level with NNL (National Ninja League) competitions. If Coach David asks a ninja to join the team, certain requirements must be met and maintained in order to keep his or her spot!
