KidStrong Stratham KidStrong Stratham provides science-based training to build strong and confident kids. We also host epic birthday parties and KidStrong Academy in Stratham.

KidStrong Stratham is a science-based training program that builds strong, confident and high-character kids, from crawling through age 11. Baby, toddler, preschool and school-age sessions are led by highly-trained coaches who take kids through age-appropriate challenges and competitions in weekly 45-minute classes. Kids run ninja courses, climb ropes, flip tires, sprint and build the foundation to excel at any sport, while practicing public speaking, teamwork, grit and problem solving to excel at life. Kids rank up and earn extra in-class responsibilities like Class Captain. 96% of parents say KidStrong is why their kids are more confident.

Big news: KidStrong is partnering with Good Inside and Dr. Becky. šŸŽ‰

Here's why this matters: KidStrong is where kids practice who they're becoming - building strength, bravery, and confidence through movement and character development on the blue floor. Good Inside gives parents the language and tools to shape who those kids are, not just how they're behaving in the moment. Together, we're helping parents raise kids who are strong inside and out.

And here's the best part - all current KidStrong members, and anyone who becomes a KidStrong member before September 13, gets 3 FREE months of a Good Inside membership*. Take the same work our coaches do on the blue floor and bring it home, so what your kid practices with us keeps building at your kitchen table too.

Strong bodies. Strong character. Strong families. That's the goal ā€” inside and out. šŸ’Ŗ

*Must redeem by September 13. Check your email for your specific redemption code.

The BOSU ball isnā€™t just a balance tool. šŸ§  Itā€™s a neuromuscular trainer. Every wobble forces your childā€™s brain and muscles to communicate at lightning speed which builds the neural pathways behind reaction time, coordination and agility. We donā€™t do random. Every tool in KidStrong has a reason. āš”
