Is there a picture or a drawing of where each of the swing positions is A 4,,A7 etc
I know where A 4 is but not sure about the rest.
i believe that they are:
A1 - set up
A2 - backswing club parallel to ground
A3 - backswing arms parallel to ground
A4 - top of backswing
A5 - downswing arms parallel to ground
A6 - downswing club parallel to ground
A7 - impact
A8 - follow thru
Here they are.
