Brea Academy
About Us
A Place Your Kids Will Actually Want to Come Back To.
Ultimate Ninjas Academy Brea is a kids' fitness and development center built around obstacle course training for children 9 months through 8 years. It's a family-owned business with a simple belief: kids grow best when they're having fun.
Our mission
Obstacle Course Training for the Next Generation.
Most kids' gyms offer open play. We offer coached, age-specific programs designed around actual child development - the kind that builds real strength, real focus, and real confidence over time.
Our curriculum isn't random. Every class has a structure. Every obstacle is chosen for a reason. Every coach knows exactly what a 4-year-old needs that a 7-year-old doesn't.
What we offer
Four Ways to Be a Ninja.
Ninja Classes
Ages 9mo – 8yr
Weekly coached classes grouped by age. Mini Ninjas (1–3), Lil Ninjas (3–5), and Jr Ninjas (5–8) - each with their own curriculum and pace.
Open Play
Ages 1–8
Open gym sessions for kids to explore every obstacle at their own pace. Enrolled students get one free session per week. Drop-ins welcome.
Birthday Parties
Private events
Private gym access, a dedicated party room, and a party host - all included. Packages for every age group and size.
Camps & Events
Seasonal
School break camps, special events, and seasonal programming. Kids spend a full day in the gym with structured challenges and ninja fun.
Why we're different
What Sets the Academy Apart.
Coached, not chaotic
Every class is instructor-led with a real curriculum - not supervised free play. Kids learn, progress, and get better each week.
Age-specific programs
We don't mix 18-month-olds and 8-year-olds. Each program is designed around what kids that age actually need, physically and developmentally.
Small class sizes
We keep classes small so every child gets individual attention. Coaches know each kid by name and track progress from session to session.
Zero prerequisites
No gymnastics background, no prior experience, no "sporty" kid required. The program is designed to meet every child where they are.
Built for confidence
Our coaches are trained to encourage without pushing. Every child works at their own level and celebrates their own milestones.
