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.


Teen 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.


Get started today and try a RISK-FREE ninja class to see if your kids will love it!

Step 1. Fill Out Waiver Form

Complete the required waiver form for class and we will contact you within 1 business day to let you know class placement openings. If you have questions before signing up, please don't hesitate to email here or Click the "Have Questions" button below!

Step 2. Attend Your Risk-Free Class

Get started on your Ninja journey by attending your first class! This class will be chosen with our guidance and confirmed by our staff.  We have a feeling your kids will love it! You won't be charged for the class until you determine it's the right fit for your family. Monthly, recurring charges will be applied once you enroll.

Step 3. Come Every Week To Class!

We look forward to seeing you every week as your ninja gains strength, confidence and friendships. Your child might even want to sign up for twice a week classes.  We can help you with that, and of course, if you ever miss a class, you can always attend make-up classes on Saturday morning.
