Olympia Ninja City - Ellisville

Category: Gymnastics Center

Happy. Health. Confident

Your first step here is signing up online. The gym's website says to choose the Ellisville location, look over the class schedule and register from there. The office keeps hours on weekdays and Saturday mornings, with Fridays wrapping up before noon and Sundays closed.

The company describes its classes as open to all ages and abilities. It says coaches give students hands-on guidance as they work through harder skills, with safety and fun both in mind. Its website reports that Olympia has been working with families since 1990. Google reviewers give it 4.9 stars across 8 reviews.

Ellisville is in St. Louis County, with 10,315 residents in 2025 per the Census Bureau. NOAA normals for 1991 to 2020 put the town at 4,586 heating degree days and 1,563 cooling degree days.

The gym blends ninja obstacle courses, tumbling and gymnastics into one program. The company says some of its courses are built for people aiming at obstacle course races, or for anyone who just wants better agility. The goal it names is kids who grow up happy, healthy and confident.

The Ellisville site lists Flipz tumbling, ninja classes at Ninja City and preschool and KinderBee gymnastics among its programs. It also runs summer camps.

Before you register, have your child's age handy. That way you can match them to the right class, from the preschool groups up to ninja and tumbling.
