[whip]

Sixth edition reads....
7-15 HIP ACTION The hip action category is included to separate the "motion" of the hips from any work they may accomplish.

The work the hip action does, is to lead and pull the shoulders back and down in varying combinations. This has very valuable applications.. Forgetting to shift the weight or clear the right hip is difficult if the hips are initiating the shoulder turn--in either direction......


Seventh edition reads slightly different...

7-15 HIP ACTION The hip action category is included to separate the "motion" of the hips from any work they may accomplish.

The work the hip action does, is to lead and pull the shoulders back and down in varying combinations. This has very valuable applications.. Forgetting to shift the weight or clear the right hip is difficult if the hips are initiating the DOWNSTROKE shoulder turn--in either direction......

Then both editions go on to say..

With swingers using the arc of approach this actuation may be executed as a throwing of the right shoulder by the hips, as in 10-19-C

Hip action must not be haphazard. It is a pivot component that must be carefully timed and sequenced to sustain the continuity and spacing of the pivot train(of components). Omitting the hip action unintentionally will disrupt the feel as well as the continuity of the entire pivot(see 6-b-3-0 regarding pivot rhythm)
