It is a broad generalization because I think you do a little of both. Just an overall feel and what you think. Backswing and downswing. For me it feels like I use more trail side pulling through the hitting zone to my finish. When the lead side works more my swing gets out of sync.Could you elaborate more? What portions of the swing?
Oh wow - that is strange!FWIW, my last instructor got some goofy thoughts in his head in the 2018/2019 off season and started having me try and "push" with my trail arm. OMG, it screwed my game up worse than a change ever has. It was so bad that I started the 2019 season at a 6.4 and after a few weeks of his instruction, I could not break 100. I ended up finding a new coach that actually knows my old instructor and he could not figure out why he would have me do that.
Interesting. I do like Shawn clement with some of his thoughts for prepping before the swing. (intermediate point, ball flight).Thought I'd might add that all muscles in the human body 'pull' even though it might sometimes equate to a push feeling when in contact with the object.
Here is a one-armed golfer that seems to just pull . One theorist would say he is the purest form of a 'A Left Arm Swinging' action but is he really only 'pulling' ?
If you look closely he does seem to have a very flat swing and is connecting his upper left arm to his left pec area. So is his left pec 'pushing' against the left arm too?
Theoretically we could say:
1. His upper body pivot and left shoulder socket is pulling his left arm down and out (like throwing a frisbee backhanded)
2. His left shoulder girdle muscles are helping to pull his left arm 'down and out ' too.
3. We have upper body pivot pushing his left pec against his upper left arm 'out' (for a certain small period of time).
So using some mix of point 1-3 , the golfer has intuitively found a 'way' (I suspect without knowing any physics of biomechanics or other golf theories ) to swing a golf club very efficiently with whatever capabilities he has at his disposal.
I think I have to agree with Shawn Clement philosophy that as humans, we are 'hard wired' to utilise forces/torques more efficiently (and safer for our body) if we let our CNS (Central Nervous System) do all the 'biomechanics' for us (ie. using our 'external focus intent on completing a task' ).
