The Benefits of Studying The Way of the Raven


Achieve fitness and lose weight! Relieve stress and increase agility. Karasu Ryu Combat JuJutsu is a method and system of Martial Arts and is an incredible workout that can whip you into shape fast while providing you with a body, mind, and spirit connection.


One of the greatest things we see as Instructors are adults consistently tapping into their potential, and realizing they are so much stronger than they thought in so many ways. Martial Arts training helps open doors you never knew you had and helps you achieve goals you never dreamed were possible. Are you ready?


In just a short period of time, you will begin to carry yourself with confidence and become the kind of person an attacker will avoid! When you have developed those skills to defend yourself, you will not feel frightened on the go. Karasu Ryu Combat JuJutsu is one of the best martial art systems for self-defense.


Imagine a workout that pushes you to be your best, where you make friends with other students who are at the same level, all while learning a skill that will make you feel strong and confident! Train like an MMA fighter for the fun of it, or train to fight in the cage either way you will have a BLAST!


Being present, at the moment, is a key part of an individual’s progress in our Way of the Raven martial arts program. Whether that is through a training drill, or interacting with an instructor, or just tuning out stresses from the day, learning to center your thoughts at the moment helps to relieve stress and be happier. We have a noble Way of the Raven philosophy that will help you reach your full potential!


For some adults, finishing what you start can be a challenge. Especially with busy work/life schedules. Through regular progress and encouragement from our instructors, adult students are pushed to reach their goals and are motivated to keep going until they succeed. What a great accomplishment!


When we think of confidence for our adult students, it’s a bit different than with kids. Adults build confidence through losing weight, toning their bodies, letting go of negativity, taking pride in something that is their own, AND, having the knowledge and skills so that they can appropriately defend themselves and/or their families. A win/win for all!


In our adult Way of the Raven classes, we look for opportunities to help students succeed by leading groups through specific leadership exercises. By encouraging participation during class, we help students to come out of their shells and lead. This allows the potential for more success at work and in all of life.
