Serving Lake St. Louis, Chesterfield, Eureka and O’Fallon in Missouri

Open Gym

Building confidence through tumbling, gymnastics, trampoline, aerial silks, birthday parties, preschool programs and private lessons that create glowing smiles!


Hi-NRG Gymnastix offers a variety of open gyms that will meet your child’s needs!

Open gyms are available for pre-schoolers, after-school gymnasts, tumbling & trampoline students, ninjas, and Aerial & FLYing athletes.

Our coaches are eager to help children reach their full potential! Hi-NRG open gyms are STRUCTURED and highly supervised by our well-trained staff. Attending an open gym is a great opportunity for additional gym time to work on a specific skill your child is wanting to conquer. Open gyms serve not only as extra gym time, but also as a make-up if your child has missed a class. It is also a wonderful chance to show your friends what your exciting sport is all about. New members are always welcome!
