| a) | proper alignments: |
| i) | height = elbow slightly bent during execution of block (not "locked out") |
| ii) | depth = blocking arm extended parallel to front knee after execution |
| iii) | width = blocking arm extended to opposite shoulder |
| iv) | palm facing horizontally upward (away from leg) |
| b) | improper execution (double factor): |
