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

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!

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 didnt want it to end.

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.

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 youre into unique training methods and need something different from your average gym!

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.

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

Hard workout staff was friendly
