Dominic says, 'I love ninja because I'm getting closer to doing the laches, which Ninja has motivated me to work harder. And I'm excited to be almost getting the bar on top of The Wall without assist. And I love everything in the gym!'

As I’m from MN, I have not been out to Ark yet. But I am leaving this five star review because of Ark being the first gym to publicly support NSC in this whole craziness. NSC is the best league and I really appreciated your statement on it. Thank you! I hope I can get out there soon!

The coaches do a fantastic job at Ark! My 10yr old daughter loves coming to class every week, and they make challenging yet achievable goals for the kids in an impressive setting. I decided to try this place for my daughter instead of gymnastics-as those environments typically breed a lot of body dysmorphia for young girls-and that is just not the environment that is fostered here at Ark. she loves getting strong!

Ark Ninja is an amazing gym to train at and would highly recommend it for anyone regardless of age and ability. The obstacles at the gym are ever changing and will keep you challenged and provide an amazing workout. What's even more amazing is Nate and the staff at Ark Ninja. Not only are they top competitors and bring that level expertise to class, they're incredibly kind and patient. The overall environment at Ark Ninja is family friendly and accepting for everyone. They have special classes for homeschoolers that we often take advantage of. Ark Ninja has a great kids and teen program as well as an amazing adult program. So something for everyone!

We live in CA but have been to The Ark twice; once for open gym (before BOC 5.0) and once for WNL Youth. Everyone has been very welcoming and my ninjas LOVE their course design.

We’ve had such a great experience with Ark Ninja! We first tried a Parents’ Night Out, and both of my kids loved it—they stayed engaged the entire 3 hours and didn’t get bored once.

Now my daughter has started taking classes, and it’s been wonderful to see her growth. She was nervous at first and worried she wouldn’t be able to do it, but the coaches have been amazing.

They’ve encouraged her, helped her make real progress, and she’s been able to do some really cool things that she didn’t think she could. Best of all, she’s feeling confident and proud of herself.

Highly recommend Ark Ninja for kids!

My daughter loves ninja. She trains wherever and whenever. We've seen a lot of ninja gyms across America. Ark Ninja is the best ninja gym, hands down. Some stuff is "simply" exceptional like the facilities or the love-of-the-sport vibe. But what sets Ark Ninja apart, and it is truly off-the-charts amazing, is the level of coaching and the student connection. The coaches have an unmatched knowledge of ninja, and they are able to coach students in multiple ways across all skill sets of ninja challenges. The fact that the gym allows the coaches to use their own personal style to connect to students is why they train so successfully. No one else does this on this level.

Whatever you are looking for in a ninja gym, Ark Ninja has it.

We LOVE Ark!!! Almost 2 years ago we took our son to a local ninja event that featured so many of his favorite ninja’s from ANW. It was the spark that started our ninja journey. So when Ark opened and we discovered several of those same athletes on the coaching staff, we knew this would be a great place for him to train. The coaches are so wonderful at explaining body movement to the kids so they can understand how to do an obstacle or how to improve. They provide honest and positive feedback to help the youngsters improve. Nate and crew are so committed to helping these young athletes reach their goals, improve their ninja skills and become even better humans. Our son has taken to each of the coaches here and learns something different from each one. Watching him improve while becoming a better teammate, all while having a blast makes us happy as parents. We are so grateful for this community and thrilled to be a part of it. No matter your skill level, Ark has something for everyone. That’s the beauty of this community.
