| a) | proper alignments: |
| i) | dimensions: |
| 1) | height - shin level |
| 2) | depth - knee slightly bent (not hyper-extended) |
| 3) | width - center of body |
| ii) | body alignments: |
| 1) | foot: |
| A) | rotated to be parallel to ground |
| B) | toes pointed directly to side (to toe slightly upward) |
| 2) | ankle slightly bent to expose inside of foot |
| 3) | upper body / hips - Twist rotation |
| iii) | Point of Contact - inside of foot |
| iv) | stance - Twist positioning |
| b) | proper formation - weapon (foot): |
| i) | foot - kept flat |
| ii) | toes: |
| 1) | extended and relatively flat (not bent forward) |
| 2) | kept together (Compact Unit) |
| c) | execution: |
| i) | Method of Execution - Thrusting |
| ii) | execute directly to target (prevent arching line of travel) |
| iii) | improper execution: |
| 1) | improper speeds / methods: |
| A) | executed too slow (transforms into push with foot) |
| B) | executed too tense (unable to achieve proper 'snap' of strike) (strike looks 'pushed' out) |
| C) | strike not tensed at Point of Contact (improper timing / never tensed) |
| 2) | improper alignments / angles: |
| A) | incorrect extension: |
| I) | not executed at all |
| B) | incorrect positioning: |
| I) | ankle over / under bent (side to side) |
Form Specific
| a) | Common execution errors: |
| i) | not executed at all (only crossover is executed) |
Comments
| a) | Common alignment errors: |
| i) | leaning away during execution |
Example of a proper instep kick (left)
(with half-knuckle)
Example of proper instep kick formation
Example of improper instep kick
formation / alignment
ankle improperly bent - too much / too forward /
too little, improper rotation - over
Examples of improper instep kick execution
improper height - high / low, width - wide,
not executed, leaning away
