Most People Show Up for One of Three Reasons.
A kid who needs confidence. A body that needs something better than the gym. A real worry about being able to protect yourself. We hear all three every week.
-
01You want your kid to have something that is theirs.
"I want my kid to build confidence, focus, and the kind of grit that does not come from a screen."
-
02The regular gym stopped doing anything for you.
"I am tired of counting reps. I want to actually learn something and get in shape while I do it."
-
03You want to know you could protect yourself.
"I do not want to feel helpless. I want to know that if it ever came to it, I would not freeze."

Who is this for?
What Training Here Actually Looks Like.
Pure Machado Lineage
We are an official Carlos Machado academy. The Jiu-Jitsu you learn here traces straight through the Machado family to Carlos Gracie: no diluted curriculum, no made-up belts.
A Room Without Ego
Beginners roll with people who protect them. Nobody is trying to prove a point on a first-timer. That is how members stay healthy and stay on the mat for years instead of months.
Taught at Your Pace
Whether you are 4 or 40, brand new or coming back after years off, instructors meet you exactly where you are. Progress is real and earned, never rushed.
Three Steps to Your First Class.

The Standard in the Room
Joshua "Cowboy" Ruiz
Carlos Machado Black Belt
Trained here from his first white-belt class in 2016 to black belt and owner.
Joshua "Cowboy" Ruiz walked into 805 as a white belt in 2016 and never left. He earned every belt on this mat and now owns the academy and leads instruction. Off the mat he has worked as a bounty hunter and executive-protection specialist since 2011, which is where his self-defense teaching comes from: real situations, taught plainly, with no ego. His standard for the room is the one in the name on the door: train smart, stay humble.

I started here with zero experience in BJJ. Coaches were patient and I never felt out of place. All the members are super nice and take it super easy on beginners. The goal is always to learn and get better. I have found myself loving BJJ and really excited to keep training here.
-
I started here with zero bjj experience and have really enjoyed the great balance of patience and challenge the instructors and more experienced students provide. Everyone here is invested in making their fellow students better, which creates a great learning experience. Thank you Josh, Ric, and Jacob!!

This is a great gym! I've been training here for a little over a year and I look forward to every class I'm able to attend. I would highly recommend this place to anyone near Simi Valley who wants to challenge themselves physically and mentally.

Place is great, coaches strive to work with everybody individually and always teach us lots while still letting us have time to roll. Good schedule for classes and tidy mats as well!

Was looking for a new gym since moving from Thousand Oaks, walked in to 805 and loved the vibe. It's a welcoming school with great instructors!

What People Always Ask
Everything You Want to Know Before You Come In.
How old does my child need to be to start?
Kids can start Brazilian Jiu-Jitsu with us at age 4 in our Kids BJJ program (ages 4 to 6), then move into Youth BJJ for ages 7 to 12, and into the adult program at 13. We also run Muay Thai for kids 6 and up. Every class is built for its age group.
What is the trial class and what does it include?
It is one full hour on the mat for $59.99. Pick any class on the schedule, show up, and train the whole session. Nothing to sign and no pressure afterwards. It is the most honest way to see if 805 is the right fit.
I have never trained before. Is that a problem?
Not at all. Most of our members walked in with zero experience. Beginners are welcome in every class, technique is broken down so it makes sense, and the room is drama-free on purpose. You will not be thrown to the wolves on day one.
What styles do you teach in Simi Valley?
Brazilian Jiu-Jitsu in both gi and no-gi, Muay Thai kickboxing, and women's self-defense, plus martial-arts fitness and conditioning. We are an official Carlos Machado academy, so the BJJ traces straight through the Machado family to Carlos Gracie.
Is BJJ safe?
BJJ has one of the lowest injury rates in martial arts. No strikes to the face, no knockouts, and live rolling is introduced only when your technique is ready. Our culture, train smart, stay humble, is built around keeping people healthy on the mat for years.
Do you have a discount for first responders or military?
Yes. Military, law enforcement, first responders, security, and healthcare workers train for $150/mo. Parents are also welcome to train free on the mat alongside their children.
What does membership cost after the trial class?
BJJ is $200/mo, Muay Thai is $150/mo, both together are $250/mo, and fitness-only is $125/mo. There is an annual paid-in-full option that includes a free uniform and two months free. We will walk you through it after your trial class.
The Quiet Cost of Waiting
A Year From Now, You'll Wish You Had Started This Week.
Everyone who has trained here for years started with one nervous first class. The only difference between them and you is the date on the calendar.
-
The confidence your kid is missing is the same confidence a year of training builds, quietly, one class at a time.
-
The "I should really get in shape" you have been saying for months becomes a skill you actually have, and a body that moves better.
-
Knowing you could protect yourself is not paranoia. It is one of the most settling things a person can carry, and it starts on day one.
