The RCW Difference

We don’t simply offer the most well rounded curriculum of any martial arts school because it’s trendy. This is our passion and myself along with our entire staff of professors and coaches made it our mission to travel the world and source the very best up to date material around. Because of this you’ll find a higher degree of safety and community that most school’s can’t match. Classes for every skill level, with opportunities to better yourself every step of the way. Whether it’s working in class with partners, attending seminars with world class experts, or competition, you’ll find it at RCW. 

Which path will you choose? 

- Kali & JKD - Kali refers to the “bladed art” and features all manner of handheld weaponry. Under the Inosanto method students learn 12 key areas of blunt, sharp, and projectile tools. Dan Inosanto is our chief instructor who is the heir apparent to Jeet Kune Do, Bruce Lee’s art and philosophy. Tailored for MMA and street self defense, it has an unrivaled depth of efficacy that can’t be matched, it’s basically Krav Maga on steroids! 

- Gracie Jiu Jitsu - Pinoeered by Helio Gracie and made famous by his sons who conquered the world in both Vale Tudo (no rules) and the UFC. Brazilian Jiu Jitsu has taken the world by storm. Because it uses principles of leverage and skeletal positioning it’s indispensable for anyone of any size, shape and age. It’s a great work out that teaches you how to neutralize any opponent on the ground. 

- Muay Thai - Known as the art of 8 limbs because of the use of knees and elbows, Muay Thai is more than a kickboxing sport. It’s the national past time of Thailand and rich in culture. It is also a military art and rapidly puts together devastating combinations from Boxing, Kickboxing, and clinch work. A Muay Thai class will get you in shape, fast! In a typical hour we usually burn 800-1000 calories. 


Muay Thai (Kick Boxing) is constantly evolving. For generations it has included the use of pugilistic strikes, knees, elbows, kicks, and clinching.

More recently there’s a strong influence of Western Boxing, along with a variety of footwork common in Southeast Asia. At RCW in Tigard we promote the art of Thai Boxing under the World Thai Boxing Association.

Whether your goal is self defense, fitness, MMA, or cross training, Muay Thai can add to your repertoire. It’s great to get in shape, meet a ton of incredible people, and learn something along the way.

I box and do muay thai and what not. But learning how to use the escrima sticks was a whole other thing. My main training has been on those, because that’s mostly what Mockingbird is known for. (…) They’re foam, so when I accidentally whack the stunt guys—which I’ve done more than once… in the face—they don’t bruise or break their nose.


Muay Thai in Portland begins with fundamentals

At RCW in Tigard we had a HUGE group of beginners getting on board in our kickboxing program. It was great to have the energy in class and take them through the basics. In this clip we are covering the jab and cross exchange. This is a basic drill designed to illustrate range, build defense and timing while delivering clean straight punches. 

The advanced group in the class (you can kind of see to the left) are taking the drill further and adding the leg kick into the mix. Progressions like these are a great way to build competency in boxing and Muay Thai before jumping into sparring. They also lay the foundations for self defense. Someone who begins their training at River City Warriors in this manner can perform clean combinations in just a few classes. New people are always welcome in our classes and find quick supporters in our long term students who are there to help. You’d be surprised how fast you can catch on, anyone can jump right into training when it’s done the right way. 

Thanks for watching and enjoy the journey. 

The hardest part about getting great training results? Simple, it’s getting started! 

The biggest barriers to an activity that will change your life happen before you ever begin! Any time you start a new habit, the mental preparation and expectations perceived can put you in a mental grid lock. You want to check out Kickboxing, but nervousness and angst set in. 

In life sometimes when opportunity knocks, you’ve got to kick the door in! At RCW we’re aces when it comes to teaching beginners. We’ve had thousands of people come through our doors over the years and the majority of all people who start training with us at our Tigard location stick for more than one year. It’s because it doesn’t matter if you pick up Muay Thai (kickboxing), Gracie Jiu Jitsu (grappling) or JKD (Bruce Lee’s method) we have a detailed curriculum and a step by step process that leads to success. In fact, we’ve never had someone who was “unteachable” or incapable of learning the skills we’re covering every day. 

The hesitation from beginning any new endeavor comes from the perceived notion and fear that makes starting worse than it is. Everyone who checks out our Muay Thai class loves it! The only people who don’t are still on the couch! 

Luckily, it’s easy to get through this if you have a PLAN. Whenever you start a new endeavor if you just feel STUCK before you get started write out a plan logically. It’ll remove some of the fear, and the key is, it’ll help you move forward even when you’re afraid. We tell kids this all the time right, courage doesn’t mean an absence of fear but the ability to work through it and still achieve our goals. A small written plan will really help you get going and it’ll take the fear out of each individual step. If you want to go a bit further write down or visualize how you’ll feel after you’ve started. What benefits have you gained, imagine yourself already attaining what you want. 

Once you get started, you’re going to blow yourself away. Once you start doing something good for yourself it’s hard to go back to the old you. If you try something empowering like Kickboxing, you’ll never want to imagine giving it up. Take some small steps in toward any endeavor, and you’ll see that it’s only the small fears that hold you back from the big goals in your life.
