If you think about it, all physical martial arts techniques have to be based on sound principles and concepts of anatomical physics, otherwise, they aren't going to work in every situation. This is the problem with most martial arts. They may look nice as an art, but when it comes to effectiveness or environmental changes, they don't always work.

The following twenty-five principles and concepts can be applied to any martial art technique to help understand exactly how and why and individual technique works. At the VALLEY JUJITSU SCHOOL, all of our techniques are based on sound principles of anatomical physics and students are taught to understand how and why each and every technique works.

Here are the Twenty-Five Principles and Concepts of Advanced Jujitsu Concepts:

1. 90/45 Degree Angle Principle
   
2. Anatomical Misalignment

10. Closing the Gap
    
11. Compression
    
12. Constriction
    
13. Dropping the Center of Gravity
    
14. Elliptical Circle
    
15. Extension / Hyperextension
