21 important points?

Characteristics of all Mechanically and Geometrically Correct Golf Strokes


1 The Stationary Post (player's head) accurately returns the Clubhead through the ball (Centered Arc)
2 The Post may turn (Pivot) but does not "Sway" or "Bob"
3 There is no wobble in the Clubshaft attachment (Grip)
4 The Hinge Assembly controls Clubface alignment
5 The Clubshaft lies full length on a flat. tilted plane
6 The Clubshaft always points to the Plane Line except when they are parallel to each other
7 The Lever Assembly is driven by exerting pressure against it
8 No portion of the Lever Assembly can swing forward independently
9 Regardless of how the Lever Assembly is driven, it moves in a circle
10 The Lever Assembly must be driven through Impact by an On Plane force, (moving towards the Plane L:ine)
11 Clubhead Force and Motion is On Plane at right angles to the Longitudinal Centre of Gravity and varies with the speed, Mass, and Swing Radius
12 Ball speed is dependent on both before Impact and after Impact Clubhead Speed
13 The Clubhead travells Down and Out until it reaches "Low Point"
14 Divots are taken "Down and Out" not just "Down"
15 The Club starts Up and In after "Low Point" but the Thrust continues Down Plane during the Follow-THrough
16 The Plane Line controls the Clubhead Line-of-Flight. Clubface alignment controls the Ball Line-of-Flight
17 The Clubface need to be square to the Line-of-Flight only at Point of Separation
18 Changing the Plane Angle has no effect on the Plane Line
19 Stance Line, Plane Line and Flight Line are normally parallel
20 For any given Line-of-Compression (through the ball) every Machine must produce identical Impact Alignments
21 The relationship of all Machine positions and motions can be described by a geometrical figure

Axiom: n. A self-evident or universally recognized truth.


I just love the 21 points in 1-L. And, I live on their principles every day in my teaching.

Lynn Blake Certified Instructors are required to memorize them and relate them individually to the major concepts of the Golf Stroke. This results in a greater depth of understanding and an increased ability to solve each student's unique swing challenges. They are far better teachers with this skill than without it.

It's very interesting (and telling) that no instructor I've met can name - let alone explain - these 21 points. While this information can be overwhelming for guys like me, it is essential to move forward. Thanks so much!! Jeff P.

1 The Stationary Post (player's head) accurately returns the Clubhead through the ball (Centered Arc)
Regardless of Axis Tilt of the body, Tripod with centered eyes.

2 The Post may turn (Pivot) but does not "Sway" or "Bob"
Provides a fixed Head height.

3 There is no wobble in the Clubshaft attachment (Grip)
The Hands are clamps. Extensor Action

4 The Hinge Assembly controls Clubface alignment
The First Imperative

5 The Clubshaft lies full length on a flat. tilted plane
When on Plane

6 The Clubshaft always points to the Plane Line except when they are parallel to each other
2-F

7 The Lever Assembly is driven by exerting pressure against it
(Note: 7 thru 11 deal with the movement of the Lever Assemblies and the Second Imperative)
Pressure is on the aft side of the shaft Pressure Points 1,2,3

8 No portion of the Lever Assembly can swing forward independently
Bent Left Wrist

9 Regardless of how the Lever Assembly is driven, it moves in a circle
Around the left Shoulder

10 The Lever Assembly must be driven through Impact by an On Plane force, (moving towards the Plane L:ine)
Swingers use Centrifugal Force, Hitters use Muscular Drive of an active Right Arm.

11 Clubhead Force and Motion is On Plane at right angles to the Longitudinal Centre of Gravity and varies with the speed, Mass, and Swing Radius
Not Clubface Motion, Sweetspot, Pressure is on the aft side of the shaft.

12 Ball speed is dependent on both before Impact and after Impact Clubhead Speed
Not from effort, but a mechanical advantage. Reference 2-E

13 The Clubhead travells Down and Out until it reaches "Low Point"
14 Divots are taken "Down and Out" not just "Down"
Reference Yoda’s drawings I posted this week.

15 The Club starts Up and In after "Low Point" but the Thrust continues Down Plane during the Follow-Through
No quitting, the right elbow is still bent at Impact and Low Point and continues to Drive or be Driven until straight which is at the end of the Follow-Through (8-11), reference 6-A-4.

16 The Plane Line controls the Clubhead Line-of-Flight. Clubface alignment controls the Ball Line-of-Flight
Both must be monitored. Imperative #3 and #1.

17 The Clubface need to be square to the Line-of-Flight only at Point of Separation
Impact and Seperation are two different points and can be up to 3/4 of an inch in difference.
The Left Hand face down the Angle of Approach at Impact.

18 Changing the Plane Angle has no effect on the Plane Line
The roof can change, but the gutter remains the same.

19 Stance Line, Plane Line and Flight Line are normally parallel
“Normally” being the key word.

20 For any given Line-of-Compression (through the ball) every Machine must produce identical Impact Alignments
Impact Alignments must match the desired shot.

21 The relationship of all Machine positions and motions can be described by a geometrical figure
Everything has a geometric relationship to everything else.

OMG, what a post!

Thanks Drew!!!

This is exactly what I was hoping for. More enlightenment. Thx.

In my opinion YODA has treated us to some of the greatest pictures ever in G.O.L.F. this week, and Drew just treated us to maybe the greatest post. Only on LBG!

Yes, this is pure GOLD. I had a MORAD instructor - didn't discuss any of this. I had a S&T instructor - didn't discuss any of this. Can't believe what I've been missing. No wonder I couldn't build a proper foundation to my golf swing. Thanks guys!

Great post Drew !

Nice work Drew!!
