Sumner Ninja and gymnastics

Super fun American ninja warrior style obstacle course gym for adults or kids! It's a chill and supportive environment for anyone who feels like trying it at any age or level. If you love the show and always wanted to try it, you can't go wrong with a trial class for ten bucks.

I am 54 and I took my 11 and 14 year old nephews here for a trial hour on a Monday at 4pm. I did it too! There were 8 in the class.
The Coach paired us off into stations. We rotated through 8 stations in an hour. It was challenging but doable. I want to fit this into MY life!

My son did a Ninja birthday party. All the kids loved it. We had boys and girls ranging 3-10, and the coaches were patient and flexible with all of them. Giving the older kids ideas to make it more challenging. From a parent perspective, the party was chill and easy as the coaches did most of the work! Would definitely do it again.

Awesome place for kids! They're super nice and helpful and very patient with little kids. My kids love it so much here that my daughter opted to come to classes here instead of gymnastics. Small class sizes & lots to keep them interested for the full hour class each week.

My 9 yo son did his first trial class a few wks ago and loved it! Very positive atmosphere and professional staff. The obstacle course had everything a ninja could possibly want. We will be back!

My niece had her birthday party here this weekend and had the best time ever ! We had kids ages 2-9 and every single one of them had a blast. The staff was so helpful and hands on and even took the time to learn the kids names in the short hour we were there ! We definitely recommend this to anyone looking for a fun interactive party !!!

Amazing facility and the coaches are fantastic!! Our kids love coming here every weekend and it's a highlight of the weekend. Probably the best ninja gym in Washington.

I had a great first experience training at Sumner Ninja. Their staff were amazing to work with, they were very knowledgable on all of the equipment at the gym and are helping me reach my training goals for spartan racing this summer! I highly recommend checking out this gym if you're into unique training methods and need something different from your average gym!

Small gym with full ninja warrior set up. We came for a birthday party and the staff was amazing at helping the kids through the course.

The only for-real ninja gym south of Seattle if not in Western Washington. Great, friendly staff who push kids and adults hard yet are supportive and safe. Highly recommend!

Awesome Ninja Warrior gym that offers classes for children & adults. David is a great coach who knows how to individually motivate each student.

We came for the adult beginner class with a pretty large group and they were very accommodating. Lots of fun was had.

David and Sarah are awesome coaches! Must visit if you are into ANW or obstacle training.

My kids just got done doing a five day summer ninja day camp and they both had a blast. This was such a positive experience for both of my kids and they didn't want it to end.

I’ve been taking classes for about a mouth. I love that I’m getting to try things I wouldn’t get the chance to in a regular gym. The staff is friendly, encouraging and helpful.

Great gym and friendly staff - would highly recommend.

Staff is very nice and supportive. Owner is very nice and knowledgeable!
