Summer Camp is a GO! 😍

With your support we are able to start Summer Camps THIS Monday June 1st! In order to adhere to St. Louis County guidelines Camps are divided into Morning and Afternoon sessions, and are week long throughout the summer.

Price per week is only $100 with a 20% sibling discount for the same week. We are trying to make this as accessible to everyone as possible by keeping the price down. There is not a partial week option/discount.

You can register for any week by clicking the link below. Session registration closes Sunday night every week for the session beginning the next day.

Here is information on the camps and COVID 19 Precautions:
*Camps are designed for ages 6-13.
*If you are feeling ill, have been exhibiting any COVID symptoms or near anyone who has, please refrain from attending camp. (You will be given a refund).
*Camps will run for the full week with the same group of students staying with the same instructor for the entirety of the week.
*There is not a partial week option.
*Staff will be on an every other week schedule to limit exposure.
*There will be a maximum of 10 students per instructor with each group maintaining 30 feet or more from each other.
*All staff will be wearing masks. Attendees are encouraged to wear masks as well.
*There will be touchless temperature checks of all staff and students at the beginning of each day.
*We will have a car drop-off/pick-up protocol in place that Coach Jamie will be handling. Only camp students and staff will be allowed in the facility.
*There will be routine obstacle and hand-washing times between each stations.
*There will not be food or drink for sale, nor will the water fountain be accessible for drinking (the touchless bottle fill-up will be accessible). Students should bring their own water bottle and small packaged snacks.
*There is no lunch break (sessions are only 3 hours!)
*There will not be any full gym open gym as we need to keep groups separate.

****There is a zero-tolerance policy for intermingling between groups. Any students wandering/interacting with other groups will be sat out and removed from camp and given a partial refund. This is to ensure the program can be continued and enjoyed by all who would like to attend.****

Just hanging around practicing our ninja skills. These two met at summer camp and anytime they have class together they pick up where they left off. 💜


When you have been working for weeks on the 8ft wall, then open gym comes around and your ninja family is there cheering you on. You finally make it the last 2 minutes before closing!! The way these boys rallied around their new friend, encouraged, cheered and pushed him was amazing! We are very proud of our ninjas!

Inspiring Kids and Adults with athletes from American Ninja Warrior!

Build self-confidence and prepare to reach higher than you ever imagined. Classes are designed and led by American Ninja Warriors who train to conquer the same obstacles seen on the NBC hit, American Ninja Warrior.

Our General Manager in St. Louis, Kirsti Pratt, can be seen on Seasons 7, 8, and 9 of the show. She loves riding her bike and hiking in nature with her dogs. Coach Kirsti says, “ One thing that I truly love is getting into deep conversation with how people think and their beliefs about the world or people. What I mean by this is truly taking interest in who they are as a person even if I just met them. I am very open-minded to other people's perspectives. This gives me the opportunity to share my love and passion which is fitness, happiness and health. The full physical, mental, emotional and spiritual that makes up a person, and how to work on balance and being the best you, you can be!”

We are so excited to be here in St. Louis to show kids and adults that FITNESS actually equals FUN with us!
