First of all, I did not read through this entire thread but I have a question that has been puzzling me for weeks now. Understand that I am fairly new to TGM and I am learning alot through LBG.com. Anyway, my question is in regards to the extensor action. The problem I am trying to understand or visualize in my mind's eye is Below Plane. I cannot see this Below Plane and I do not understand what it looks like or what I am trying to feel with the hands. What I think I understand is that Below Plane is directly underneath the plane line somewhere in the dirt. If possible, could someone please help me understand so that I can visualize the Below Plane--thanks.
