Ninja Classes for Parent/Tot

Side Kicks is a captivating class, encouraging little Ninjas to engage with their peers as they warm up and practice their physical and social skills! The coaches, along with parents, will guide the "sidekicks" through an easy to navigate obstacle course - no ninja experience required! The children feel great about themselves as they practice and improve gross motor skills, balance and agility.


Ninja Classes for Junior Ninjas (ages 4-5)

Junior Ninjas: Junior Ninja is a lead up to the full sized obstacles that are used at USA Ninja Challenge. Junior Ninjas (ages 4-5) develop their ninja skills with smaller, easy-to-navigate obstacles until they are ready for the full scale equipment.


Ninja Classes for Kids

Ninja fitness classes give kids an immersive experience into the sport of Ninja. Children are introduced to a variety of obstacles and an interactive learning program. Your child will have a blast while learning fitness and life skills.


Middle School Fitness Classes

The teen warrior training classes consist of warm-ups and slightly more intensive ninja exercises, including a range of obstacles that changes from class to class. Teens will focus on the fundamentals of swinging, climbing, jumping, traversing, balance, tumbling and floor skills, as well as participate in creative conditioning sessions.
