We drove up from Omaha to participate in one of their competitions and it was amazing. A real class act here at the gym. The owners and staff are engaging, professional, and focused on helping your kids grow. Swing by and watch how much fun your kids have on the obstacle course!

Thad Stanfill Parent

My son has been going to 605 Ninja for several years and absolutely loves it. He's not into traditional team sports, this was the perfect fit for him. Everyone is welcome, no matter their fitness level and the coaches are encouraging, fun and supportive. The facilities are clean, updated and bright.

Amy Pownell Parent

The atmosphere is fun and the owners go out of their way to make sure everyone is safe and feels comfortable in the space. Also, the open gym pass is a GREAT way (especially in the summer) to burn the kids' energy!

Was here for my little brother's birthday party. The staff were great and the place was clean. Would definitely come again.

Sabrina Lush Customer

We attended an open gym session and a ninja warrior competition at 605 Ninja. Both were fantastic experiences! The staff there are amazing. They worked with any child who needed help and they were so patient and kind.

Jennifer Prewitt Customer

We had a great silks party! All of the staff were welcoming, organized, and excited to be there. The facility was clean. The music and atmosphere in the silks room was fun and festive-loved the colored lights! August's energy was contagious and helped make the party fun for everyone and she made the birthday girls feel special! Thank you!
