The typical and ineffective arm position at the completion of the entry is shown below. Note that the arm is parallel to the surface.
This position is ineffective because:
- the leverage is very poor,
- time is wasted before the arm is in position to generate propulsion, and
- there is unnecessary stress on the shoulder.
An effective arm entry requires a downward angle so that at the completion of the entry, the hand is the below the elbow and shoulder.
This position is effective because:
- the leverage is improved,
- wasted time is eliminated,
- shoulder stress is minimized.
