I definitely believe there is an easier way to try and do this without having to think so much.
I have always believed in trying to get players to understand where the low point of the swing has to be. If the ball is on the ground the turf interaction has to be on the target side of the ball.
Considering most right handed golfers are right hand dominant, trying to get them to focus on their non-dominant hand/wrist was almost impossible.
I have done a lot of work with the PGA HOPE Program, a golf program for Veterans and wounded Veterans. When I was able to get right handed golfers that did not have a left arm to bottom the club out on the target side of the ball, I knew it was possible for everyone.
During lessons I will have a full swing area with the ball and a full swing practice area next to the ball. In the practice area I will put a mark down, a line that signifies the ball. In their practice swing they have to bottom the club out on the target side of that line. It is something that most people can practice away from the range.
The key is to make sure you have a proper weight shift into the lead/front leg and then in essence feel like you are throwing the clubhead into the turf left of the mark/ball. You need to feel that first and then see what the divot patterns are like. If the divots are to deep we focus on trying to brush the ground target side of the mark/ball. The feeling is that the shoulders are staying on plane and the trail shoulder will cover the ball at impact.
By trying to obtain the low point of the swing on the target side of the mark/ball in this manner, it is a much less technical concept then tying to focus on pronation and supination.
