No personal insults on either side please. Usually when a thread gets to this point its either getting really interesting or really overworked. There is still some good subject matter here if y'all can keep your cool. One warning - this thread now has MikeO's attention so which pill do you want; red or blue? |
The left knee move is more than a stable base, it is a critical part of why Hogan could create lag pressure the way he did.
Many of those that learned from Hogan speak of moving the left knee as a key start to the downswing. It is well worth trying if you are a swinger. |

A couple of observations on the two pics (drill vs. real) and your comments would be appreciated . . . 1. Shifting focus a bit to the right knee. Note that the spacing between the knees is much better in Hogan's "real" pic. The right leg is MUCH straighter at Start Down than in the "drill" pic. Also there is probably less flexion in the right knee than there was at address at this point. The right side gets "saggy" in the drill . . . would this be due to the COG you described above going parallel to the target line? 2. Is there a "direction" for the left knee in creating the forces you describe above? Should the left knee maintain its flexion AND move toward the target at startdown? 3. At what point in the stroke do the hips lose their flexion in the downswing? Or do should they? See below . .. THIS  OR THIS?    |

You can try maintain flexion with your left knee although this won't work for people. Hogan was able to maintain knee flexion was a reaction from being able to create normal and shear forces. The down swing acceleration the center of pressure shifts forward toward the front foot. It is this action creating forward momentum that facilitates the production of shear force at the feet/ground interface. Ground reaction to the shear force created by the feet produces a force couple, which is translated through the legs to the hips segment.This creates lower body stabilization and maintain left knee flexion. The force couple acts on the hips segment to produce torque and rotary acceleration. How hogan created Lag was a chain of events, in his initial downswing Hogan created separation between his lower body and upper body. This loaded his muscle group between his hips and upper body relationship. The stabilization of Hogans lower body allowed Hogan to fire his upper body with his muscles.His arms Lagged behind and his muscles in is upper body arms relationship loaded, As his upper body started to slow prior to impact, This again allowed hogan to fire the muscles (arm /upper body).His upper body would momentarily slow and square up to his hips at impact.The slowing of the upper body allow hogan to fire his arms. Hogan arms fired and they slowed down just prior to impact allowing hogan to release the club. This is how hogan created Lag. It's a little more complex than this although I hope this gives a general understanding. Hogans secret was a chain of the events although his key to his golf swing was the ability to create ground forces. With out ground force you can not maintain knee flexion like hogan did. A chain of events lead to how Hogan created Lag. In golf people don't know how to create ground forces. Although even if they are aware of them it's not something you can physically apply on the practice fairway. You need to train your body the right movement patterns to create ground forces. What is important is how you create the right moves to create ground forces. Took years of research to work out how to train someone to achieve ground forces, research found the body has to be trained to achieve ground forces. |

Daryl what do you mean by these lines, none of these are representing the axis of the spine, shoulders and hips are in space. The hips, shoulders and spine have turned and open left of the target. These lines are according to the target line. They aren't representing in reference to the axis of the spine, where the spine is in space. The center of mass has moved towards the left foot and the shoulders and hips have turn around the axis of the spine left. these lines aren't indicating or are a good reference to whether or not the hips and shoulders are perpendicular to the spine. Can you explain what these lines are trying to indicate? Bucket, In my reply to Edz will may be shed some light. We don't every worry about knee flexions etc. how far hips left etc. Huge secret and key is if you have created the right ground forces this take care of the lower body mechanics, hips speed, how far the hips turn, acceleration and deceleration. sliding and so one. The theory was created 20 years ago, although taken years to work how on earth to teach someone to how do this. Although was natural. If you train your body how it wants to naturally create speed or anatomically designed to move. This happens for you. Next toughest part working out how to train the body how to move the way it's designed to. Years of research and testing. |
Sorry Bio, I should have added comment. The photo's aren't mine. I don't know what the lines represent.
I uploaded the photo sequence to illustrate that Ben Hogan's Hip often led his shoulders well into the Finish. Examples of Hogan were posted illustrating parallel Hips and Shoulders at Impact and I thought that those didn't represent Hogan entirely. |
