This place has been wonderful for my child. They have multiple classes and have them capped at a good limit to make sure all kids are being helped and to grow in the course. They change the classes up often to make it new and exciting each class. The staff and team are kind and so helpful. Birthday parties are done right and very reasonably priced for classes and parties.

We’ve had such a great experience at Ultimate Ninjas Noblesville! The staff is caring and engaging with the kids. My son loves coming back week after week for his class. He has grown so much in his strength and confidence.
They are always coming up with new ideas for camps and events too. Cami was super helpful and accommodating when I had an online issue scheduling. Before we were even regular customers, I was in the building for something else looking for a changing table for my infant daughter. One of the Ninjas staff saw me, came out and told me to come into their space to use their restrooms and changing table. It was a small moment but stuck with me. We’ve had the same level of care and attention ever since!

We had our boys birthday party at ultimate ninja Noblesville & it was fantastic! The staff members, Jake, Jami, & Braxton were amazing! They kept the kids engaged and taught them how to utilize different parts of the ninja course. They also offered to help with serving food, as well as clean up when we were in the party room. Truly could not have asked for a better experience!

We hosted our 5-year-old's birthday here and am very pleased with the entire process. The team checked in via email or call at three different points the week before the birthday to outline all details and answer any questions. I'm a bit OCD, and they were not at all inconvenienced by my detailed questions.

The area is accommodating for all ages. There were a variety of activities everyone could choose from, and I always find it a delight when parents can enjoy the party as much as the kids. We had parents challenging themselves to the courses and playing alongside their children. Coach Zion and Rob, both very personable and interactive with the children.

The party room provided plenty of space for my party of 30. There is generous seating, refrigeration, and personal decorations allowed. I had free rein to decorate the room however I wanted, as long as it didn’t cause any permanent damage. The staff were very polite and always checked to see what our needs were.

I recommend Ultimate Ninja for your next birthday celebration!

The coaches at Ultimate Ninja Noblesville are incredibly welcoming and kind. We traveled to Indiana from out of state, and my boys quickly found a gym family away from home. It was immediately apparent that the staff cares deeply about their students' development as athletes and people. We cannot wait to go back this summer!

Our children’s interests have changed over the years, but Ultimate Ninja is by far the best experience we’ve had at any gym in Hamilton county/indy. Not only is it a great activity to really challenge our kids in a positive way, but what has really exceeded expectations for us is the community and staff they have built here.

I’ve never seen such positivity and excitement for kids as the staff cheers on every new milestone and accomplishment. All of the coaches are incredible and truly rooting for each child to succeed. Major shoutout to Braxton as well, as his excitement and care for everyone is contagious across the entire gym.

Frequently Asked Questions

FAQ

Home

What ages can start at Ultimate Ninjas?

Lil Ninjas and academy tracks start around age 3. Full gym classes and open play are built for 6+. Adult fitness (ULTIFIT) is a separate program at many gyms.

Is an obstacle gym actually safe for kids?

Yes when it's coached and padded. Coaches scale obstacles, foam and mats are part of the floor, and nobody gets forced onto a line they're not ready for.

How do I pick a gym versus an Academy?

Gyms (the full Ultimate Ninjas locations) are the bigger obstacle floors with classes, open play, parties, and camps. Academies are smaller training sites — still classes, open play, parties, and camps, just a tighter footprint. Use the location finder for whichever is closer.

Do I have to book everything in advance?

Classes, parties, and camps: yes if you want a guaranteed spot. Open play: reserve when you can; walk-ins only if the session isn't full.

Can adults get on the course?

At most gyms, yes — waived adults can join open play or party blocks. ULTIFIT is the dedicated adult program where it exists. Academy rules can be tighter; check that site's page.

What should kids wear?

Close-fitting athletic clothes and closed-toe shoes that grip. No flip-flops, dress clothes, or jewelry that catches on holds. Bring water.

Is there a way to try before buying a membership?

Yes. Most locations offer a free or trial class so your kid can meet coaches and try the floor first.

How do waivers work?

Everyone who steps on the floor needs a signed waiver, including adults. They're location-specific — sign the one for the gym or academy you're visiting.

What if my kid has never done anything like this?

That's most first visits. Coaches start easy and keep it playful. Nobody gets pushed onto an obstacle they aren't ready for.
