let go of every part of your body except the high side hip and the arm that's about to spear. Don't think about the feet or the currently extended arm. Use the high side hip to push the spearing arm forward
Anchor your hand in the water in front of you and "leave it there" while you stroke your body past it. You want ti visualize that your hand is not moving at all. The rest of the body will travel past it.

You need to have supple and relaxed shoulders, elbows & wrist while still applying pressure int he water to hold your place in order to look as silky as terry and shinji do.
