Modern Day Ninja Training

MMA and Parkour Classes Reimagined

At the Nexus we specialize in teaching a First Nations self-defense called Guardian Art. Guardian Art takes MMA and parkour, and fuses them 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 that come from our art 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.


Bouncier than a spring floor, our airtrick will get you the extra air you need to train your tricks and flips. We actually have the first airtrick custom designed to transform into different shapes, so it can be set up as a long runway or a nice big rectangle.

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 a Jedi. Proceeds from your registration will go towards protecting the environment. We want to begin your hero training by helping the world.

Closed Labor Day Weekend

All locations will be closed September 3-5 for Labor Day. And in honor of this, I would like to communicate my appreciation to the staff at NXGA. Since we are normally open 6 days a week, our staff make many sacrifices to teach our students. Things such as birthday parties, weddings, baby showers occur during the times we open, which means sacrifice with scheduling is frequently made. And with the bay area being so expensive to live in, many of our staff are also working other jobs. But what is most appreciated is the life force they put into their teaching, their love for the students, their passion to continue training to get better not for themselves, but for others. To them it is not a job, it is being part of a dream. I’ve come to realize that since students and parents only see us while we teach, they may not see us as anything else other than teachers. The reality is that when Guardians are not teaching, we are working on preparing and executing missions that involve traveling around the world to aid in places where it is needed. So for the times we close, I hope it is not viewed in a negative way, but rather in a more supportive way since we are using that time to practice what we preach. -Condor
