Golf Master Tips, The Art of Golf, Swing Dont Hit, Feel Dont Think - The golfer in photo 1 has good rhythm-: i) Note that he has pivot-rotated his torso well through impact so that his navel points about 45+ degrees to the left. ii) Note that his swinging arms are rotating at the same speed as his rotating torso - an imaginary line drawn equidistant between the two straight arms points at his navel. iii) Note that his clubshaft is swinging at the same rotational speed as his swinging arms and rotating torso - the butt end of the clubshaft points at his navel.
The golfer in photo 2 has poor rhythm. Note that his torso has stalled at impact and his navel is facing the ball-target line. Note that his arms have traveled faster than his rotating torso. Note that his clubshaft has traveled faster than his arms.
This chosen photo-comparison example is a deliberate exaggeration designed to make an important golf instructional point. The important golf instructional point is that a left arm swinger must swing rhythmically through impact, so that that he can look like the golfer in photo 1 by the end of the followthrough (defined as the time-point when both arms are straight).

The Art of Golf, Swing Dont Hit, Feel Dont Think
I believe that a major factor that allows a golfer to have perfect "rhythm" through the impact zone is the factor of an "efficient pivot-rotation action" - a golfer must continue to efficiently rotate his torso after impact. Many high handicap golfers stall their pivot at impact, and the arms/clubshaft (which have gained considerable angular momentum) then travel faster than the torso. Consider what will happen if the torso slows down, or stalls, at impact.
In a good golfer's swing, note where the left shoulder socket will be at the end of the followthrough - see photo 1. The left shoulder socket is moving up-and-away from the ball, and that up-and-away motion of the left shoulder socket allows the left humerus to easily externally rotate in the left shoulder socket.
In a good golfer's swing, note where the left shoulder socket will be at the end of the followthrough - see photo 1. The left shoulder socket is moving up-and-away from the ball, and that up-and-away motion of the left shoulder socket allows the left humerus to easily externally rotate in the left shoulder socket.
Consider what will happen if a golfer's pivot action stalls at, or near, impact. The left shoulder socket will not be moving up-and-away from the ball, and it will therefore be harder for the left humerus to rotate easily in the left shoulder socket (which is required for a horizontal hinging action).
If there is impedance to rotation of the left humerus at left shoulder socket level, then most of the rotation of the left forearm/hand/clubface will occur due to biomechanical movements happening below elbow level, at the level of the left forearm - the left forearm will supinate as the radius bone rotates around the longitudinal axis of the ulna bone.
That will cause the back of the flat left wrist/hand to face more groundwards and this will predispose to duck-hooked shots (shots that fly low and leftwards) if the clubface rotates groundwards during impact.
Consider the "two-handed basketball pass" again.
Note that the ball thrower has his hands on opposite sides of the ball at roughly the level of the ball's equator. Note that when he throws the ball at the target, that the hands remain at roughly the same horizontal level - there is no counterclockwise rotation of the hands during the throw action.

Two-handed basketball pass - from reference number [3]
Note that the ball thrower has his hands on opposite sides of the ball at roughly the level of the ball's equator. Note that when he throws the ball at the target, that the hands remain at roughly the same horizontal level - there is no counterclockwise rotation of the hands during the throw action.
I believe that it is only easilypossible to throw the ball in that neutral manner if the thrower rotates his upper torso well during the throw action, so that there is no impedance to external rotation of the left humerus in the left shoulder socket.
If the thrower throws his arms towards the target without simultaneously rotating his torso towards the target, then his hands will likely undergo a counterclockwise motion during the throw action - the left hand will supinate towards the 6 o'clock position while the right hand will pronate towards the 12 o'clock position.
That counterclockwise rotation of the hands is not necessarily desirable in a two-handed basketball throw action towards a target that is to left of the thrower, and it is especially not desirable in a golfer's swing action through the impact zone. A golfer should never allow his flat left wrist/hand (and therefore clubface) to rotate groundwards during impact, or immediately post-impact, due to a deliberate or passively-uncontrolled left forearm rotational motion (occurring below left elbow level).
Amazingly, AJ Bonar deliberately recommends this left hand supination action through impact - seehttp://www.golf.com/golf/instruction/article/0,28136,1565175-1,00.html
Note that the knuckles of his left hand are facing groundwards post-impact - image 3.
That underdesirable hand action (called a crossover hand release action) will occur passively/uncontrollably if a golfer fails to pivot-rotate his torso efficiently through impact - for reasons previously explained.
The left hand must not supinate, and the right hand must not pronate, soon after impact, and if a golfer ensures that his torso pivot-rotates efficiently post-impact, then this undersirable crossover hand release action is less likely to happen.
Here is a good example of an efficient post-impact torso rotation and an excellent horizontal hinging action (where the left arm's rotation occurs at the level of the left shoulder socket, while the left shoulder socket is moving up-and-away from the ball).
Jack Nicklaus' swing - http://www.youtube.com/watch?v=aJ87eGG0svo
Note how well Jack Nicklaus rotates his torso post-impact. Note that he has excellent "ryhthm" - note that his arms remain in front of his rotating torso, and note that the clubshaft roughly points at his navel, throughout the followthrough phase of his swing.

Jack Nicklaus' swing action - capture images from his swing video
Note how well Jack Nicklaus rotates his torso post-impact. Note that he has excellent "ryhthm" - note that his arms remain in front of his rotating torso, and note that the clubshaft roughly points at his navel, throughout the followthrough phase of his swing.
Note that the radial border of his left forearm does not rotate counterclockwise/groundwards, and note that his flat left wrist/hand remains vertical to the ground - thus demonstrating that he is not using a left forearm supinatory rotational movement during his followthrough.
Note that the right forearm does not pronate the right hand over a supinating left hand during the followthrough (as occurs in an uncontrolled hand crossover release action) - note that the radial border of his right forearm faces skywards during the entire followthrough.
Note that his efficient torso rotation post-impact gives one the impression that he is "swinging left". The concept of "swinging left" is often misunderstood. Jack Nicklaus is not "swinging left" - he is merely rotating efficiently post-impact, so that he can keep the clubshaft on his "selected" impact plane from impact to the 4th parallel.

Many golfers do not keep their clubshaft on their "selected" impact plane post-impact and they allow the clubshaft to centrifugally release in a direction that is slightly to the right of the target.
Look at Kevin Na's driver swing in this swing video - http://www.youtube.com/watch?v=E0EKksPTyk0
If one looks at this swing video of Kevin Na's swing at a normal speed, it may appear that he is flinging his club centrifugally down-the-line in a direction that is slightly right-of-the-target. However, when studying his swing frame-by-frame using a swing analyser program, one can see that he is keeping the clubshaft on his selected plane through the impact zone.

If one looks at this swing video of Kevin Na's swing at a normal speed, it may appear that he is flinging his club centrifugally down-the-line in a direction that is slightly right-of-the-target. However, when studying his swing frame-by-frame using a swing analyser program, one can see that he is keeping the clubshaft on his selected plane through the impact zone.
Image 1 shows Kevin Na's clubshaft in the mid-downswing, and he is progressively shallowing his clubshaft from the TSP to the elbow plane. His clubshaft reaches the elbow plane when he gets to the delivery position (3rd parallel). His clubshaft then remains on the elbow plane during the release swivel phase of the downswing and it is on the elbow plane at impact (image 2).
At the end of the followthrough (image 3), his clubshaft is still traveling along the elbow plane. Image 4 shows the time-point when his hands disappear from view as the club passes the 4th parallel. Note the movement of the left shoulder between image 2 and image 4 - the left shoulder is moving up-and-away due to his continued post-impact torso rotation, and his excellent torso rotation allows him to execute a horizontal hinging action while keeping the clubshaft on-plane.
His clubshaft should not be moving inside-left sooner after impact, because that would mean that he is pulling his clubshaft off its selected plane of travel - a plane intermediate in steepness between the elbow plane and the turned shoulder plane plane.
If a golfer selects to swing on a shallower plane (eg. impact zone plane that is closer to the hand plane than the elbow plane) through the impact zone, then his hands will disappear from view sooner (when viewed from a down-the-line view). The hands will also move inside-left sooner when a golfer uses a short iron, because the clubhead swingarc has a smaller radius and the hands are held closer to the body.
The concept of "swinging left" after impact should therefore be understood as being the appropriate biomechanical actions that a golfer needs to execute to efficiently keep the clubshaft on his selected plane as the clubshaft moves through the impact zone - from the 3rd parallel to the 4th parallel. A key part of those "appropriate biomechanical actions" is the biomechanical fact that a golfer needs to continue to actively pivot-rotate to the left post-impact, so that the left shoulder moves up-and-away.

A key part of those "appropriate biomechanical actions" is the biomechanical fact that a golfer needs to continue to actively pivot-rotate to the left post-impact, so that the left shoulder moves up-and-away.
The movement of the left shoulder socket up-and-away (inside-left) allows a golfer to efficiently perform a horizontal hinging action while keeping the clubshaft on the selected plane. When the club is released in the late downswing, it is moving in-to-out towards impact at a very fast speed, and it requires a very efficient post-impact pivot rotation (inside-left movement of the left shoulder socket) to keep the clubshaft on the selected impact plane between impact and the 4th parallel.
The "feeling" that a golfer should experience when performing this appropriate post-impact pivot-rotation action is the "feeling" of "swinging left". If a golfer "swings left" with maximum efficiency during the followthrough, then the golfer should be able to effortlessly transition from a horizontal hinging action into a finish swivel action, that ultimately leads to an efficiently completed finish action.
When a golfer "swings left" there are variations in swing style because of the variable element of timing/rhythm. I previously stated that the optimum swing, from a rhythm perspective, has an optimally synchronised coordination of movement between the rotating torso and the rotating arms.

If one looks at Kevin Na's swing, one can see that his arms are not moving in perfect rotational synchrony with his rotating torso during the downswing and followthrough - although he is "swinging left". The best swing example of perfect synchrony (optimum rhythm) that I have ever seen is Ben Hogan's swing. See - http://www.youtube.com/watch?v=LJdChWnxDvU
Note how synchronously he rotates his arms/torso throughout the downswing and followthrough. Ben Hogan is "swinging left" with perfect rhythm, and I think that he remains a perfect role model for modern-day golfers.
Here is an example of a golfer who seems to be "swinging left" to a greater degree than most professional golfers. Hunter Mahan - http://www.youtube.com/watch?v=YLxfropD-FU
In this series of photos captured from his swing video, it appears that Hunter Mahan is "swinging left" sooner than most professional golfers - note how his hands are disappearing around the left side of his body in the late followthrough (image 4).
The reason for that visual phenomenon is that Hunter Mahan's selected impact plane is shallower than usual - note that his clubshaft is just above the hand plane at impact (image 1) - compared to Kevin Na, whose clubshaft is closer to the turned shoulder plane at impact (see image 2 in the photo series of Kevin Na's swing above).

When Hunter Mahan "swings left" he is doing nothing more than staying on his selected impact plane during the followthrough (images 2, 3 and 4), and he "appears" to be "swinging left" more than most professional golfers because his selected impact plane is shallower than average.
I think that it is advantageous for a golfer to select a shallower impact plane, because it means that a golfer is more likely to remain more "rhythmically connected" during the downswing and followthrough (like Ben Hogan and Hunter Mahan) - a swing scenario where the arms and body are more synchronously coordinated as the golfer swings through the impact zone (from the 3rd parallel to the 4th parallel).
