[12 piece bucket]

Ballard and a few less known, Mike Wine, etc.
have preached a tringular structure is created and maintained throughout the swing.
In TGM view when swinging does the triangle that is formed at address maintain structure and position relative to the chest throughout the swing?

Different question:
if one wanted to set up and swing from the impact fix position, what must be done differently than when starting from an adjusted address position?

Their triangle doesn't change shapes. TGM's changes shapes by changing the length of one side (BENDING THE RIGHT ELBOW) . . . Law of the triangle.
