Ages 3–17

Four Ways to Build an Unstoppable Kid

Whether they're shy or fearless, 3 or 17 — there's a program designed for them

Ages 3-17

Obstacle Course Classes

Progressive, coached classes where kids level up at their own pace. They walk in nervous — within weeks they're climbing things they never thought possible.

Full Day

Summer & Holiday Camps

Full-day camps where kids make real friendships, conquer new challenges daily, and come home exhausted (in the best way). The camp they'll talk about all year.

Private Events

Birthday Parties

The birthday party kids actually beg for. Private obstacle course, a dedicated host, and every kid goes home saying "best party ever."

Drop-In

Open Gym Sessions

No commitment, no schedule. Kids practice at their own pace, challenge friends, and burn off every last ounce of energy.

Frequently Asked Questions

Yes, 100%. If you change your mind for any reason, you get a full refund. If you keep it, your deposit converts to a class credit when we open. There is zero risk.

It means the discount you lock in today stays with you as long as you're a member. When tuition goes up (and it will as we grow), your rate stays the same. Founding members are permanently grandfathered in at the lower rate.

Ages 3 to 17. Classes are grouped by age and ability so every kid gets the right challenge level. Tiny ninjas (3-5) have their own equipment and coaching style. Teens get advanced courses that push their limits.

First 5 Families members get one free birthday party (normally $350). Private obstacle course time, a dedicated party host, setup and cleanup handled. It's the easiest party you'll ever throw.

September 2026. We're at 441 Defense Highway in Annapolis, MD. Construction begins soon. Pre-registered families will get progress updates and early scheduling access before anyone else.

441 Defense Highway, Annapolis, MD 21401. Easy access from Route 50, about 10 minutes from downtown Annapolis and convenient for families in Crofton, Bowie, Severna Park, and Arnold.

Trampoline parks are drop-in entertainment — kids bounce around for an hour and leave. We're a progressive skill-building program with coached classes, level tracking, and real measurable growth. Your kid earns levels, builds strength, and develops discipline they carry into school and life. It's the difference between babysitting and building character.

Full refund. No questions, no hoops. We're already in lease negotiations at 441 Defense Highway with construction planned — but if anything changes, every penny comes back to you. That's the whole point of the 100% money-back guarantee.

Absolutely. Most of our students have never done anything like this before. Our coaches meet every kid where they are. The obstacles are adjustable, and progress is individual. Some of our most dedicated ninjas started as the shy kid in the back.
