Hip Action

[Daryl]

7-15 HIP ACTION The Hip Action Category is included to separate the “motion” of the Hips form any work they may accomplish.
The work the Hip Action does, is to lead and pull the Shoulder back and down in varying combinations. This has very valuable applications. Forgetting to shift the weight to clear the Right Hip is difficult if the Hips are initiating the Shoulder Turn – in either direction. Study 2-N and 7-3. With Swingers using the Arc of Approach (2-J-3), 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-O regarding Pivot Rhythm.

Hip Action performs work.
The amount of work Hip Action can perform is directly related to the amount of Weight Transfer. The amount of weight transferred to the right foot on the backstroke, determines the amount of weight that can be shifted onto the Left Foot (Heel) before and as Startdown. The amount of weight transferred determines the force generated by Hip Action. The speed of the weight transfer has little if anything to do with the amount of Hip Action. Be Deliberate, not Speedy.
Pitch Shots can have a soft Hip Action. Accomplish this by transferring almost no extra weight to the Right Foot during the Backstroke. Full Shots require the most amount of Hip Action Work and 80% of weight should be transferred to the Right Foot during the Backstroke and that much transferred to the Left Foot (Heel) during Startdown and Downstroke and Release as the Hips Slide, then Turn.

1. Hip Action sustains Pivot Lag (and Accumulator and Clubhead)
2. Hip Action Pulls the Shoulders and Arms at Startdown, during the Downstroke and Release and Impact
3. Hip Action precludes any Arm or Shoulder muscle involvement
4. Hip Action propels the Hands through to Low Point (without any perceived upper body muscle involvement)
5. Hip Action amount variation, varies the amount of pressure of the #3 Pressure Point.
6. No amount of Upper Body or Arm Strength can equal the Forces generated by an average amount of Hip Action.
7. Hip Action is effortless.

I cannot understand the biomechanics of why 80% of one's body weight should end up over the right foot as a result of the backswing pivot action movement. Could you please explain the causal biomechnanical connection between a backswing hip action movement (cause) and body weight movement to the right foot (effect) that allows you to claim that 80% of body weight should end up over the right foot at the end-backswing position?

You also state that increased weight transfer increases the force that can be exerted by the downswing hip action move. On "what" is that force exerted?

? clubshaft? ? clubhead ? left leg ? left foot.

You also state that hip action propels the hands to the low point without any upper body muscular effort. Could you please explain the biomechanics of that phenomenon?

You also state that the hip action exerts more force than upper body/arm action. Are you claiming that this applies to the force exerted on the clubshaft or ball? If so, could you please explain the biomechanical/physics mechanism.

Weight and Weight Transfer supply the energy for Hip Action. Hip Action moves the Shoulders.

The Weight should not end up over the Right Foot. The Hips need only Turn during the Backstroke. The weight shifts (Direction of Force) to the instep of the Right Foot during the Backswing. The more weight that can be shifted/directed to the Right Foot, the more weight can be shifted to the Left foot during startdown. Shifting Weight supplies the energy behind Hip Action. The amount of weight determines the amount of energy-force created.

You also state that increased weight transfer increases the force that can be exerted by the downswing hip action move. On "what" is that force exerted?
If the Left Heel is raised (pulled) above the ground during the Backstroke Hip Turn, then the Left Hip lowers and the Right Hip Raises (Standard Knee Action). As the Left Heel is lowered to the ground during Startdown, the Left Knee Straightens and The Right Knee bends which Raises the Left Hip and Lowers the Right Hip. This can be performed with or without a shift in Weight. If without, then it’s simply a Hip Turn and allows Shoulder Rotation. But with a Weight Transfer, Hip Action is created because a Force has been generated to Throw the Right Shoulder Downplane. The more Weight Transfered, the greater the force. The Transfer moves weight from the Instep of the Right Foot to the Left Foot Heel. The more weight, then the more Left Leg Muscle used to straighten the Left Knee which increases force raising the Left Hip. The greater the force raising the Left Hip, then the Greater the force pulling the Right Shoulder Downplane. Keep in mind that at the Top of your Backswing, your Left Shoulder is as Low as it will ever be. You cannot force the left shoulder upward (with torso muscle because that doesn't force the club downward), but you can force the right shoulder downward. That's Hip Action. Otherwise, at startdown, you end up using torso muscle to spin the shoulders and pull on the arms. no-no.

You also state that hip action propels the hands to the low point without any upper body muscular effort. Could you please explain the bio mechanics of that phenomenon?
See Above. The force that propels the Power Package will not diminish until the Right Shoulder speed diminishes. Low Point, Straight Right Arm.

You also state that the hip action exerts more force than upper body/arm action. Are you claiming that this applies to the force exerted on the clubshaft or ball? If so, could you please explain the bio mechanical/physics mechanism.
Hip Action Forces are exerted on the Right Shoulder and Power Package and in turn on the Primary Lever and Ball and #3 pressure Point. Your Pivot supplies all of the force and effort in a Golf Swing (Swingers). Power Package transport should be performed entirely by the Pivot. The Power Package, including Left Wrist Cock will stay intact until release if Hip Action is used. Any pulling with the Arms or turning of the shoulders with torso muscle will cause immediate and premature throwout of the Secondary Lever. Some people can play this way but expend great effort and distance is erratic with all clubs.
An ever present question/mystery is how can a 120lb LPGA Player hit a Drive 250 yards. I believe that you don’t have to be strong enough to perform one push-up to hit a Golf Ball 250 yards.

Hip Action should be learned and Zone 1 should be mastered.

I can accept your belief that a primary hip action move (pelvic shift-rotation movement) at the start of the downswing helps the right shoulder move in a downplane direction. However, you seem to be implying that the efficacy of this phenomenon is dependent on the degree of weight transfer that occurs during the backswing, and that the force of the right shoulder throw is dependent on the amount of weight transfer from right-to-left at the start of the downswing. You stated "Shifting Weight supplies the energy behind Hip Action. The amount of weight determines the amount of energy-force created." I know of no scientific evidence, or biomechanical evidentiary reasoning, that supports your assertion. Here is a link to a swing video of Shawn Clement swinging off one-leg.

He can hit the ball as far on one-leg - where there is no weight transfer and no ability to push off the right instep - as he can when hitting off two legs.

You also seem to be implying that there is a causal link between the amount of weight transfer and the ability of the left leg muscles to straighten the left leg. However, you have not provided any biomechanical evidentiary reasoning to show how weight transfer causes the left leg to straighten faster, or more efficiently.

Finally, there is a school of thought (eg. Peter Croker) that implies that the hip action should be secondary to the active movement of the upper body and arms pulling the grip end of the club down towards the ball (essentially a right shoulder/right arm throw action that ensures that the power package assembly remains intact). Do you have any evidence to support a belief that is not an equally viable method of initiating the downswing?

Dear Jeff,

This is a Discusion Forum. Are you up for a discussion?

However, if you want to pull down with the arms, or swing on one Leg, then keep doing so.

7-15 HIP ACTION ....................

1. Hip Action sustains Pivot Lag (and Accumulator and Clubhead)
2. Hip Action Pulls the Shoulders and Arms at Startdown, during the Downstroke and Release and Impact
3. Hip Action precludes any Arm or Shoulder muscle involvement
4. Hip Action propels the Hands through to Low Point (without any perceived upper body muscle involvement)
5. Hip Action amount variation, varies the amount of pressure of the #3 Pressure Point.
6. No amount of Upper Body or Arm Strength can equal the Forces generated by an average amount of Hip Action.
7. Hip Action is effortless.

"Hip action (rotate or slide or both)" is "Pivot-controlled hands" and releases "Pivot Lag (and Accumulator and Clubhead)", whereas "Hip reaction (to the hands and shoulders)" is "Hands-controlled pivot" and sustains "Pivot Lag (and Accumulator and Clubhead)".

To the eyes, the hip moves first and starts the down swing and seems like an action. But, in fact, it reacts to the actions of the shoulders and hands, despite of moving the first and seeming to start the downswing, and should be regarded as a reaction.

The reason it (or actually the knees) always moves the first is because the counterforce comes from the ground.

It moves first doesn't means you do the same way. As a matter of fact, you shouldn't.

You rotate and pull (or push), the "Law" takes care the rest, including "firing the hips".

So weight transfer is a key to more power,force & distance...the more the better....how can these trick shot guys generate so much distance when they get on their knees and hit balls. I think in some commercial Tiger knocks the cover off a ball from his knees. Is that all upper body strength with the lower body acting as a stable platform?

I thought that I was up for a discussion - by posting so many questions and challenges.

I simply cannot understand the basis for any belief in an ironclad causal connection between weight transfer and clubhead speed. If anybody can present a coherent argument establishing a causal connection - I would appreciate it.

Hg - it is amazing to see trick shot golfers hit the ball 300 yards off their knees. One can see Ben Witter doing that in one of his U-tube videos. He not only hits a golf ball 300 yards off his knees - he does it when kneeling on a 2 foot diameter exercise ball.

V.J. Trolio has a some very interesting comments about
the force: "As you turn and move left, placing the center
of mass over the left leg, the head will go down, the left
knee will increase flex, and a force will be felt into the
ground under the left foot. This is longitudinal force.
Once the force is in the ground (martial arts calls this
rooting) then the instep of the right foot and the large
muscles of the left leg and gluts are used to create sheer
forces (forces that run parrallel to the surface of the
ground) for extreme rotational ability. Whit that said, make
sure you feel the downward rooting into the ground."
