Modern Day Ninja Training

MMA and Parkour Classes Reimagined

At the Nexus we specialize in teaching a self-defense called Guardian Art. Guardian Art takes MMA and parkour, and fuses it back together like how ancient ninja training once was.  We then built state of the art facilities to take it to the future.

More jungle than gym

Martial arts schools have been around for ages, but none offer training grounds like our Nexuses.  We chose the name Nexus, because it is a hub for so many different types of training such as parkour, freerunning, tricking, karate, self-defense, martial arts, and ninja warrior. It’s like an indoor theme park for ninjas.

Tryout and Tour a Nexus

Ninja Obstacle Courses

Built for Guardian Art.  Also, for training parkour and obstacle courses like Tough Mudder, Ninja Warrior, or the Spartan Race.  No parkour gyms match the safety of a Nexus. We went to the extremes of padding everything up.


Whether you're a monkey or into calisthenics, our bar setup is so fun you won't mind getting blisters. And don't be surprised if you see targets hanging from them to train strikes on swinging objects.


A tricking and freerunning dream! Check out this new technology that makes foam pits a thing of the past.

Sign up for a tryout to begin

Start by trying out to see if Guardian Art is the right fit.  You’ll get to tour our facility and break a sweat learning to move like Daredevil. It is just $10, and all proceeds will go towards protecting the environment.  We want to begin your hero training by helping the world.
