| a) | proper alignments: |

| ii) | depth = front foot 1 1/2 length of foot from rear foot |
| iii) | height = bend of supporting leg such that the opposite knee is at calf level of the supporting leg |
| b) | proper rotation: |
| i) | feet = front - directly backward / rear - backward at 45 degree angle |
| ii) | body = backward at 45 degree angle |
| c) | proper weight distribution: |
| i) | 10% / 90% - weight and positioning primarily over rear foot |
| d) | proper positioning: |
