If one thinks a while about the 'reasons' to do certain things in the swing - the physics, geometry and anatomy of the motion, that path is defined fairly well for a given person, shot, condition. Multiple sources of info are very helpful, but ONLY if you know the overall perspective they are coming from - which of the three areas they address, and which of the 'too much, not enough and just right' they are discussing.

Each of those three areas has an 'ideal' as far as the 'clubs' motion and as far as how the body must move to support it. The obvious difficulty is that each person and each shot is unique, so unless every golf tip or article spells out clearly the perspective their approach is coming from, it is easy to get confused.


All of that said, the swing can be summed up with:

The 3 imperatives
The 3 essentials

"support the on plane swinging force in balance"


Those cover the physics and geometry for the most part. Austin did a great job of looking at how the body must move to support the club. From what I have heard and understand of Mac, he has done a lot of work in that area too.

So many variables, but the CONCEPTS are not that difficult. The big advantage to TGM is that it 'should' be the basis for teaching every student of the game the proper concepts - the 'map' of where you want to go - How you decide to get there has many options, different roads to travel. That first turn, each grip type, leads you down a different road, but you still are trying to get to the same destination - the support of impact, the application of FORCE - sustaining the line of compression.
