Building strength, confidence & self-esteem

Helping kids succeed one obstacle at a time


The #1 reason children quit is because sports are no longer fun. Our program is about having fun while building physical fitness. It is a complete, well-rounded fitness program encompassing strength, coordination, agility, speed, and self-confidence.


Our class-based progressive training encourages ninjas to work hard while having fun going through the obstacles.
The flexibility of our obstacles insures that every ninja is working at their own level with the ability to progress to higher levels. When ninjas see progress, they become motivated and invested in the program.

Our certified trainers keep it fun by assisting each ninja to master new obstacles and providing positive reinforcement.

Discover the benefits of ninja and establish healthy habits for life.
