*We are combining some of our age groups in order to keep siblings together as much as possible.

* Some start times are not exactly on the hour as we want to allow enough time for cleaning between classes. 

*We roll admission so please call when ready to begin. Find more details on our schedule page or call to get a spot on the roster.

*Children can begin classes ANYTIME but classes do fill!  We do not run sessions and new children start every week!  Our memberships run month to month and the most common question we get is "is it too late to sign up?".  The answer is no, we have all levels of ability in our classes and challenge each child at their level. Classes do fill fast so sign up soon if you are ready to get started!  

What USA Ninja Challenge is all About

USA Ninja Challenge is a year-round obstacle course training program that combines basic skill sets from gymnastics, climbing, cross training, and track and field. The sport of Ninja is quickly becoming the most fun and creative way to meet the physical needs of today’s kids! Ninja Challenge is open to boys and girls ages 4 to 17.

Our class program has 6 levels to master with a wide variety of progressions, drills and challenges to tackle. Ninjas that demonstrate their mastery of skills advance to the next level of training.

Social Benefits of Physical Activity


Confidence is key to a good social life; physical activity helps with that. As you become stronger and faster, your self-confidence will grow, you’ll be able to take pride in the physical things you can now do and appreciate the progress you’ve made.


Physical activity can also help your concentration skills, by providing a release valve for stress and pressure and encouraging higher levels of endorphins. If you can concentrate well on important work and social tasks, you’ll be happier overall.


Being social is most enjoyable when you feel good about yourself, have a positive self-image and high self-esteem. Exercise can help with that. By maintaining a healthy weight and an uplifted mood, you’ll feel better about yourself and can engage in social activities fully and frequently.

Social Life

One of the biggest social benefits of exercise is just that – an improved social life. Especially if you participate in team sports or exercise with a group, you’ll develop greater empathy and social skills. You’ll also make new friends and gain new social outlets.
