    Posted: 15 February 2010 at 5:42pm
During practice sessions over the last week I have visualized several different techniques of moving the weight into the left heel on the downswing. The technique that has worked best is one I have not found in any forum on this website and I wanted to get some feedback. From the top of the backswing, I imagine my left hip traveling in a direction 45 degrees to the left of the target line (for reference, I am saying moving down the target line would represent 0 degrees and moving perpendicular to the target line would be 90 degrees). Each time I execute this move properly the weight moves into my left heel, my left glute is activated, and I am automatically put into NJA. Did I stumble onto something solid here.....?

First time poster...a +1 hcp from VA...appreciate your thoughts.

houck,

RST does talk about an external rotation of the left hip that helps to pull the weight back into the left side, most importantly the left heel.  This is the biomechanical explanation of how to properly achieve a proper weight transfer back into the left side, but obviously it feels different to each individual as feel and real always does.  I believe, unless I am misinterpreting your description, that you are describing this external rotation.

Thank you houck510!

The weight transfer videos, parts 1, 2, and 3 is always a great refresher for understanding a proper weight shift.

Not wanting to be too picky but the manual says to externally rotate the left leg, not the left hipWink

"The proper sequence of the downswing is as follows:1.      Externally rotate the left leg to move the knee directly over the left ankle"
 
I have been studying hard and spotted your deliberate mistakeBig smile

Colin.earl,
I think item 1. is correct, because if you want to move knee over the left ankle (toward the target) you must rotate the leg externally.
My opinion, "item no.4: pull the left oblique to rotate the hip 45*..." makes me very confusing now. The oblique muscle connect rib cage and hip frame, if you want to rotate hip, you have to fix the rib cage but you are not hanging by the shoulder so can not use oblique to rotate the hip. You must continuously use the hip adduction muscle (inner thigh) to rotate the hip to "click" NJA position (45*)
Everyone correct me if smt wrong otherwise I will get worse with my misunderstanding.

Sonadt,
I got very confused when we talked about the oblique muscles in the past.
There are 4 of them, internal and external, right and left. The internals pull in a different direction to the externals. So the internal of one side works with the external of the other.
The hip adductors, by definition, only pull toward the middle line of the body. I am not sure they can rotate any structure.
This is the extent of my knowledge, so I hope it is correct, and helps.

Matt,
My thinking is that: in order to apply the movement from the muscle you need to fix one end and pull the other end (muscle is contractive). In backswing, you fix the hip to the ground by all the muscle from the hip down to the ground so you can use oblique muscles to pull the rib cage to rotate the upper torso. Opposite movement when you hang by your hand, you fix your shoulder (then the rib cage as well) and you can rotate the hip by using your oblique muscles.
During the downswing, you can not fix the shoulder/rib cage (no muscle or other bone connect it to the fixed place) so you can not use oblique muscle to pull the hip around the rib cage (try to test by rotating the hip in case you fix the shoulder and don't fix the shoulder and check your oblique muscles during those movement). And the hip rotation can only work with the lower parts which connect directly to the ground (fixed place).
I do some finding and think that the inner thigh muscles which support thigh external rotation around the hip will help the hip rotated when you fix the thighbone (femur).
All analysis above is my private opinion, I also need someone help to correct if wrong.

Sonadt,
Yes I think I understand your points.  And your explanation seems right to me.
Perhaps this is the reason that I have never felt the obliques working in the downswing, but I can feel them working in the backswing, because I fix the pelvis to the ground for this to happen.

Matt,
I'm sure the obliques working fine for me during backswing as well.
