| a) | improper alignments / dimensions : |
| i) | improper block width (not at edge of body / too wide) (Outer Rim) |
| ii) | improper block depth (too close / far) (Invisible Box) |
| iii) | improper block height (too low / too high) (Outer Rim) |
| i) | hand is not completely closed when executing blocks (minor and/or major) |
| ii) | improper arm / hand positioning / rotation |
| iii) | not creating proper Angle of Deflection |
| iv) | not keeping back straight (leaning) |
| v) | head not facing correct direction |
| 1) | shoulders not relaxed (hunched) |
| 2) | overall muscles not relaxed (too tense) |
| vii) | improper foot positioning / rotation |
| i) | executed with wrong Method of Execution |
| ii) | not executing the block smoothly - i.e. mechanical / staccato motion |
| iii) | not obeying Economy of Motion principle: |
| 1) | not executing the block from Point of Origin (making a cock a separate motion) |
| 2) | executing block outside the Outer Rim / Invisible Box (also see improper alignments) |
| 3) | not executing the block on a direct Path of Travel |
Note: The above analysis also applies to double factor blocks.
Note: Typically stance, body, and head positioning is not considered part of most defensive analysis. But, because one of the key goals of American Kenpo forms is the proper coordination between the upper and lower body, these are mentioned here and in the other relevant sections of this chapter.
Note: Certain general errors that are more commonly seen for specific types of defensive maneuvers (such as leaning) will be repeated in that maneuver's section. This is to call attention to the error and how common it is for that specific type of maneuver.
