Amazing gym with amazing coaches!!! I highly recommend KOR!! -Amy​​

Kor Komplex should be the starting point of a child's athletic career. It teaches core strength (big deal), balance, discipline, agility, etc etc in ways that no other sport(s) teach in my opinion. The staff is 2nd to none and my son has made serious progress in just 8 months. HIGHLY RECOMMENDED!!!!! 6 STARS OUT OF 5  -Joshua 

Amazing place for the whole family to have a great time. The trainers are all nice, easy to work with, and encouraging. Plus it's one of the cheaper places to take the kids. Will definitely be returning.  -Devin

​ *Obstacles in St. Louis, Birthday Parties in St. Louis, Mud run

*We kindly ask you to sign your child up for class prior to coming! -Thank you

While we welcome families of all ages, typically our class program/open gym starts at age 5 due to the fact most of our obstacles are built for that age and up.





Join us for a half-day summer camp (9am-12pm) led by Ninja Warrior Specialists. The youth ninja’s will be shown basic primal movements, practice on obstacles, play mini games, learn parkour skills, and dash through course runs.

Invite your siblings and friends! We are welcoming all children ranging from 5-12 years old. KOR Komplex will be privately closed down for camp, letting us utilize both gym spaces we have. We will be separating children in their age groups once they arrive. Experienced and non-experienced ninjas welcome.

Included in Camp:

"Fun, Functional, Family environment to experience all levels of fitness." 

"I originally started my business because I wanted to help individuals take control of their health and wellness, and live happier and more active lives.
Over the years I realized that I could only help so many people with a business that focused just on personal training, and I knew if I wanted to reach more people I would need to create an open gym environment with additional modalities.  I wanted to create something different and unique.  I realized that there was a need for a fitness center where families could go and share the positive experience of fitness, so my goal became to create a facility for people of all ages to exercise and enjoy challenging and fun activities. With my interest in American ninja warrior, my knowledge in core and functional training, and personal experiences in athletic training, I decided to renovate my gym and created the indoor playground we now call the Komplex. "
