Happy Gym Builds Confidence, Coordination and Some Seriously Cool Gymnastics Skills 

A gym just for little kids has one purpose: to work for babies through 7 year olds. Our “just right” sized equipment fits their bodies. Our creative and custom curriculum matches their developmental needs. And our coaches are trained in early childhood movement, the quirks of this age group, and insider knowledge of how little kids learn best. 

At Happy Gym, we’re focused on giving little kids a supportive and comfortable place to move their body, try new things, and confidently grow into the person they’re becoming. 

The early childhood years are the most critical window for development. That’s why we designed our whole gym around this really unique time of growth. If we nail it, everything that comes after (sports, coordination, confidence, classroom skills) will be built on a rock-solid foundation. 

So whether your kiddo is flipping over the back of the couch – or needs time to warm up before jumping in – we meet them where they are and give them exactly what they need to feel safe, comfortable and confident. 

Let's Do This!

HG Level 1

5-7 years old

50 mins

Level 1 Lionhearts is where big kid energy meets bigger gymnastics skills- cartwheels level up into round-offs, handstands get held a little longer, and jumps on beam start landing with a little more swagger. We keep the energy high and the fun front and center, but this is where progressions and skills grow for our early elementary kids. HG Level 1 gymnasts build on the fundamentals - learning proper technique, through skill-focused instruction on vault, bars, beam, floor and TumblTrak. And yes—you better believe there are SOOO many cartwheels, the ultimate move for school recess 😉! Join us in Level 1!

“My child has always struggled with balance, but the progress at Happy Gym has been remarkable. She’s more coordinated and more confident. We’re thankful for Coach Sarah and the whole team—my kids look forward to every visit and love telling us about it afterward.”

Let Them Be Little

Early childhood is kinda our thing. We focus on what’s physically, emotionally and cognitively appropriate for your kiddos’ age. At Happy Gym, we let them be little while they explore, learn and grow at their own pace.

Age-level Learning

Yeah, this is preschool gymnastics, but we are keeping things rigorous and age-appropriate. From learning how to line up, to falling safely (hello, playground skills!), we help your kiddo build skills that’ll last way beyond the gym.

Celebrate Their Swagger

Every kiddo is a rockstar in their own way, and we celebrate that swagger! We meet each child where they are, helping them grow stronger and more confident with each new skill they learn.
