My Gym Children’s Fitness Center is coming to Wellesley Square in winter 2026 with a goal of keeping kids ages three months to ten years active and fit. Offerings in the former Rock the Spectrum space at 34 Central St. will include foundational mobility, gymnastics, dance, Gym Ninjas, camps, and special events, all age-appropriate, all with the goal of supporting healthy childhood development.
The space has a history of being something of a rumpus room over at least the past 40 years. In a good way. We Rock the Spectrum brought joy to the space for four years as a sensory gym, a place where kids never had to say they were sorry for who they were.
Before that, Wellesley Kidville, a self-described “happy place” for families, kept the space full of energy and fun as a pre-school, camp, art/music/dance studio, playground, salon, and birthday party center for seven years.
And many in town will remember Rugged Bear, which closed in 2011 after decades outfitting Wellesley kids in winter gear, scout and private school uniforms, and sensible play clothes.
No matter what’s been in that corner spot in the Square, any kid who burst through the doors had to play on one thing. That ramp. Sure Wellesley has brand-new playgrounds, beautiful gyms, fields galore. But the Rugged Bear/Kidville/Rock the Spectrum/My Gym ramp is probably the most popular piece of play equipment ever to make Wellesley kids happy (if not always their parents).
My Gym is one of five brands under the Momentum Enterprises umbrella and reinforces Momentum’s commitment to creating year-round opportunities for play and growth.
“Opening our eleventh My Gym location in Wellesley is an exciting milestone for Momentum Enterprises,” said Ryan Debin, CEO and Founder of Momentum Enterprises. “Everything we do is rooted in helping families feel connected, supported, and inspired. We’re proud to bring a space to Wellesley where we can increase “Smile-Watt Hours” to children as they move, grow, and build confidence.”
