| a) | proper alignments: |
| i) | dimensions: |
| 1) | height - jaw to temple |
| 2) | depth - elbow bent (not hyper-extended) |
| 3) | width - same side of body as striking hand |
| ii) | body alignments: |
| 1) | hand - vertical (palm perpendicular to ground) |
| 2) | wrist kept straight (not bent up / down and / or side-to-side) |
| 3) | elbow below strike (anchored) |
| 4) | shoulders - relaxed |
| 5) | upper body / hips - Neutral Bow rotation |
| 6) | legs / feet - Neutral Bow rotation |
| iii) | Point of Contact - index / middle finger back of knuckles |
| iv) | stance - Neutral Bow |
| b) | proper formation - weapon (hand): |
| i) | fingers - standard fist (tightly bent and kept together to form Compact Unit) |
| ii) | thumb: |
| 1) | wrapped under bent fingers (Compact Unit) |
| 2) | do not allow to separate from contact with fingers |
| c) | execution: |
| i) | Method of Execution - Snapping |
| ii) | execute directly to target (prevent cocking) |
| iii) | improper execution: |
| 1) | improper speeds / methods: |
| A) | executed too slow (transforms into push - not snap) |
| B) | executed too fast (stance settle unable to keep up with strike) |
| C) | executed too tense (unable to achieve proper 'snap' of strike) (strike looks 'pushed' out) |
| D) | strike not tensed at Point of Contact (improper timing / never tensed) |
| 2) | improper alignments / angles: |
| A) | incorrect elbow bend: |
| I) | over bent (full reach of strike not achieved) |
| II) | too-extended (elbow hyper-extended) |
Comments
| a) | Common execution errors: |
| i) | over rotate beyond a Neutral Bow (or into Forward Bow) |
| ii) | over reach - elbow not kept bent (hyper extended) |
Example of a proper outward back-knuckle (left / right)
(front / rear hand)
Example of proper back-knuckle formation
Examples of improper back-knuckle formation / alignment
wrist back backward, thumb not tucked,
wrist bent forward, hanging thumb
Examples of improper back-knuckle execution
(rear hand)
improper height - high / low, width - narrow / wide
stance over rotated, over reach - bending with elbow extended
Examples of improper back-knuckle execution
(front hand)
improper height - high / low, width - narrow / wide
stance over rotated, over reach - bending with elbow extended
