Ever wonder what happens between all the Serious Fun?

Between every class, we sanitize high touch areas and small equipment. We also clean our LEGO pieces, Magna Tiles, and gym mats daily, vacuum the gym twice a day, and finish every night with a thorough deep clean. Plus, our amazing professional cleaning team helps us keep the entire space fresh, sparkling, and ready for more Serious Fun!

Friendships grow here too! 😊 At The Little Gym, kids aren’t just building physical skills. They’re learning how to share, communicate, take turns, build confidence, and connect with others.

It’s all part of our Three Dimensional Learning approach, helping little ones grow socially, emotionally, and physically while having Serious Fun!
