Carlos Machado Black Belt
Trained here from his first white-belt class in 2016 to black belt and owner.
Joshua "Cowboy" Ruiz
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.

This is gym is so good! The coaches here are very patient and understanding with the kids. It is so hard to find a place that takes the time to educate and train my son, we're so glad we found this gym! 100% recommend!

I recently enrolled my son, and he absolutely loves the training and the coaches, Josh and Chris. The coaches have so much patience, and make the class so fun. Abdiel looks forward to this after school activity every day. Thank you for teaching him self defense and confidence training he loves.

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!
Every Question Adults Ask Before Signing Up.
Can I start if I am out of shape?
Yes. Every class meets you at your current fitness level and builds from there. Conditioning is a result of training, not a requirement to start. You do not need to get fit before you walk in.
I am in my 40s or 50s. Is this for me?
Absolutely. Some of our most consistent and technical members started later in life. BJJ rewards patience and problem-solving over athleticism, and coaches train adult bodies realistically.
What is the difference between BJJ and Muay Thai?
Brazilian Jiu-Jitsu is grappling: control, leverage, and ground-game self-defense that works regardless of size. Muay Thai is striking: punches, kicks, knees, elbows, and a serious workout. Both build real capability, and many adults train both (bundled at a discount).
How often should I come per week?
Two to three classes a week produces steady progress. With sessions running up to six days a week, including 6 AM and 11 AM adult classes and evenings, most schedules can fit it.
What gear do I need?
Nothing for the trial class, just comfortable athletic clothes and a water bottle. Training is barefoot on the mat. If you continue, we will tell you exactly what to buy for the program you choose.
Will I have to spar right away?
No. Live rolling and sparring are introduced only when you and your coach agree you are ready. There is no timeline pressure and no expectation that you spar before you can do it safely.
Is it safe?
BJJ has one of the lowest injury rates of any martial art, and our no-ego culture keeps training controlled. New students drill technique before any live work, and intensity is always calibrated per person.
Do you have a discount for those who serve?
Yes. Military, law enforcement, first responders, security, and healthcare workers train for $150/mo. See our service-member page for details.
How does the trial class work?
It is one full hour on the mat for $59.99. Pick a start date, show up, and train as much as you want: BJJ, Muay Thai, fitness. No long-term contract to try it.
