Summer Camps


Looking for something AMAZING to offer your kids over break? Send them to Ultimate Ninjas Camps, where they will learn how to tackle obstacles as seen in the hit TV show American Ninja Warrior. At Ultimate Ninjas it's so much fun to get back up and try again.....

At Ultimate Ninjas, we instill self-confidence, acceptance, and a true hunger for tackling obstacles with a positive mindset. The best part: we have a BLAST doing it! Led by 3 time American Ninja Warrior competitor Kirsti Pratt, you will not find a more positive environment where kids can show up, be valued for exactly who they are, and discover what they are uniquely capable of achieving.

During camp, kids are grouped together by age and rotate through stations where they are coached on each obstacle. After learning how to tackle the obstacles, they have time for open play so they can pick their favorites and spend extra time on the obstacles they want to master or just enjoy! At the end of camp all kids will get a chance to run through the course with their coaches just like you see on TV!


$45 each session, weekly sign up is $205 | 50% sibling discount

COVID-19 Safety Procedures
Birthday Parties - Parties now available!
We are so excited to start hosting your parties again! Our top priority is the safety of the community we have here in St. Louis. In accordance with the county's most current guidelines our parties might look a little different than what you may remember. Here is what you can expect at your Ultimate Ninjas Party!
  • There is a maximum of 40 for all parties.
  • The entire staff will be required to wear face masks throughout the party. In addition you and your guests will also be required to wear a face mask throughout the party unless you are exercising, getting a drink or water, or in the back party room having cake, snacks, etc.
  • Before being allowed to enter the facility, all guests will need to be screened with a quick verbal questionnaire and temperature check. In addition to screening every guest must have their own waiver filled out prior to arriving. The person booking the party will be responsible for sending a list of guests to the gym no less than 24 hours prior to party start time. No one without a waiver or that fails the screening/temperature check will be allowed into the facility.
  • Once checked in, your party must remain together. Similar to parties in the past we will rotate as a group from one half of the gym to the other. After rotating, that area of the gym will be thoroughly cleaned and sanitized by the staff. It is very important that you communicate with our staff if you need to leave the group for any reason and follow their instructions.
  • There will be no ball sports at this time during the party - this includes basketball and dodge ball.
  • Once in the party room you will not be allowed to re-enter the gym space unless accompanied by a staff member. At the end of the party you will be exiting through a separate door within the party room.
Kids Classes
Classes are up and ready for students AND parents! Starting July 6th students are allowed to have guests in the facility to watch and cheer them on. In accordance with St. Louis guidelines, social distancing will be in effect for family groups, and we ask that you do not intermingle between groups. It is recomended that students limit visitors to 1 guest. Unless participating in class, or getting a drink of water a facemask is required to be worn while in the facility. All visitors and students will need to be screened wearing their facemask before entering the facility. A quick verbal questionnaire and temperature check for all participants including our staff will be required. In additon to screening, every guest must have thier own waiver filled out prior to arriving. Please check and make sure you have the newest verison of the waiver filled out! We are also allowing for drop in classes, but they must be preregistered with the gym no more than 48 hours prior to class. You can reach us at (636) 206-8550. Classes are limited. If there is a specific time or age group you are looking for, please reach out to us and we will try to add in new classes as we increase our class selections.

What our customershave to say about us

We just threw my daughter’s 6th birthday party here and it was wonderful! They were very helpful and accommodating. Our guests had a great time and the staff assigned to help our party could not have been nicer. I would recommend this for a party venue (or just a fun open play/class activity) to anyone!Hannah B.
I brought my 11YO son today for open gym and he absolutely loved it! It definitely became more crowded after 12:30, but the staff was great and offered assistance when requested. The obstacles were just like the show and are easy to try, but challenging to master. We will be back for sure!Amy J.
