What is Open Gym?
Open Gym is parent-supervised, unstructured playtime inside a professional gymnastics facility. Kids have access to gymnastics equipment including trampolines, mats, bars, beams, and obstacle setups — all in a safe, spacious environment.
Unlike a structured class, Open Gym lets kids direct their own play. Some kids practice skills they're learning in class. Others just want to jump. Both are exactly right.

Weekdays: $25 per child, or $40 for two siblings
Sundays: $30 per child, or $50 for two siblings
We also offer a Frequent PLAY Card (weekdays only). $180 for a 10-pack

Who is Open Gym Best For?
Open Gym is a safe, parent-supervised space where kids can explore, practice, and play—with coaches nearby to guide and support when needed . It’s less about structure and more about building confidence, independence, and a love for being active.

Toddlers & Babies
Toddlers and babies exploring movement for the first time are building the foundations of coordination, balance, and confidence. In a safe, play-based environment, they can crawl, climb, and discover how their bodies move—developing motor skills, independence, and a love for movement through fun, guided exploration.
Active Kids
Active kids who need somewhere to burn off energy on weekend mornings can run, jump, and play in a safe, structured space—staying active, building skills, and having fun before the day really begins.
Open Gym on weekday mornings is perfect for kids who don’t follow a traditional school schedule—like homeschoolers, toddlers, preschoolers, and little ones with flexible routines. It’s a fun, safe space to move, play, and socialize while building coordination, confidence, and friendships.


Current Gymnasts
Current GymWorld students who want extra practice time can use Open Gym to reinforce skills, build strength, and gain confidence in a fun, low-pressure environment. It’s the perfect chance to get more time on the equipment and keep progressing outside of class.
Families New to Gymnastics
Families new to gymnastics who want a low-pressure introduction can explore, play, and try basic skills at their own pace in a fun, supportive environment—no experience needed, just curiosity and a willingness to move.


Building Community
Parents looking for a fun, social outing in Marin can enjoy an easy, relaxed way for kids to play, move, and make friends while families connect with one another. Community is at the heart of what we do—building connections inside the gym that carry far beyond it. Kids learn, grow, and support each other here, creating friendships and confidence that extend into everyday life outside the gym.
