7-17 Swinging from the feet
 

A Start Down that begins at the Feet (and that ultimately pulls the Power Package downward toward the Ball) gives the Stroke maximum Swing Radius (7-17). A Start Down that begins from the Knees gives less. And from the Hips still less. And from the Shoulders, even less.

So, the longest possible Swing Radius begins at the Feet. A Start Down that begins from any other Component shortens the Swing Radius and therefore produces less Power for any given Hand Speed.

Regarding the properly executed Hip Slide:

It will not result in a Sway (4th Snare / 3-F-7-D). In fact, it is exactly this 'Hula Hula' flexibility that produces the Axis (Spine) Tilt (7-14) necessary for the Line Delivery Paths (10-23-A/B/C/D) and ultimately the Automatic and Snap Releases of 10-24.

The Hula Hula flexibility (7-14) refers to the independent yet coordinate movement of the Hips and Shoulders while maintaining the Fixed Pivot Center (the recommended Stationary Head or its alternate, the "Between the Shoulders" Center). The Line Delivery Paths and the On Plane Downstroke Shoulder Turn (10-13-D) require that the Axis of the Stroke (the Spine) be tilted, and this, in turn, requires the Downstroke Hip Slide (Weight Shift) of 10-14-A or 10-14-B. This is a move that is very easy to exaggerate (7-14) and thus produce the distorted alignments that makes it impossible for the Hands to do their job (7-12).

Ideally, you would work with a competent instructor to program the correct Pivot. Whether this is possible or not, I recommend imitating the pictures in 9-1. Be sure to look, Look LOOK as you go through the 'Body Only' Twelve Sections of the Stroke to make sure that you are doing it right.

Concentrate especially on clearing the Right Hip in Start Up (9-4) and maintaining the On Plane Right Shoulder in Start Down (9-7). These two Sections are especially crucial because players who have Pivot problems almost always lack the Educated Hands necessary to get them through an On Line Start Down (3-B, 5-0, 6-G-0 and 12-3-0). I would also practice diligently the DownstrokeWaggle (3-F-5). Monitor each of the Pivot Components (especially the Hips and Shoulders) in each of the Downstroke Sections (Start Down through the Follow-Through) as you simultaneously monitor The Hands to insure that they maintain their On Plane alignments per the Mechanical Checklist of 12-3-0. This will train the Pivot to accomplish its necessary functions and, at the same time, to "get out of the way of the Hands."

At the end of the day, you must return your attention to your Hands and their Flat Left Wrist, Clubhead Lag and Plane Line Tracing. Only in his way can you maintain the essential geometry of the Stroke (2-N-0 and 2-F) and achieve the Hand-Controlled Pivot of The Golfing Machine.

With the Standard Action (Lifted Left Heel per 10-17-A), simply lower the Heel and let that action begin the Downstroke Sequence (6-M-1). If the Heel has not been Lifted, begin the Sequence with the Loading of the Flat Left Foot (10-17-C).
