I took 4 twelve year olds there for open gym night and they LOVED it (so did I... they were exhausted afterwards!!!). They kept talking about how awesome one of the staff members was. Thank you Justin Moss for making the night awesome for these boys!!!

I came in from Kansas City and brought me two children to the ninja course. We had the best time. There was a boy there named Nick who is so helpful and made it so much fun for my kids. He taught us how to do many of the obstacles and was amazing ! We would come back for sure next time we are in town.

All of the instructors are fantastic. They do a great job at pushing the kids to work hard and try for more while keeping them safe and helping them set realistic goals. And they are just as excited as the young person when a goal is met.

Great place, my kids love it. They offer a flexible class schedule and also offer camps! All instructors are fun and encouraging. Coach Nick was awesome, all four kids loved working with him during camp. He was energetic, positive and fun while keeping obstacles safe.

My kids absolutely love this gym! They did the opening weekend open play, the first Pro Camp and we can't wait for the next one! We just had my oldest's birthday party there and it was fabulous! All the kids had a great time and the employees were awesome with them! It was nice rotating through the sections of the gym where it was just our party and the kids were able to continuously do the obstacles. They went home tired that evening! Great job Kirsti, Matt and Christian!

Ultimate Ninjas St. Louis is the place to go if you:- Are a parent and want to give your child/children a place to be physically active in a new, exciting and safe way- Are an adult and have a desire to challenge yourself- Are searching for family fun opportunities that don't involve a screen- Are an aspiring Ninja and need to get the feel for obstacles replicating the specs and finish seen on the showUltimate Ninjas St. Louis has friendly, knowledgeable and professional staff. The facility is clean, has ample parking and the obstacles are professionally constructed and well maintained.The aspect I like most about this gym versus other obstacle-focused gyms I've visited is the wide open feel of the space. Ultimate Ninjas St. Louis doesn't feel crowded and hasn't tried to pack too many obstacles into a tiny space, which is something I've experienced at other "Ninja" gyms across the country.I haven't attended any of the adult or child classes they offer, only the open gym sessions.
