PERFECT explanations, thank you. Answered all of my (current) questions AND some!
If it weren't so early in the morning after a night of restless sleep, I would run out to the garage right now and apply the tips offered to see how I'm currently set up. Heck, I even have a plumb-line somewhere (from my days of competitve handgun shooting).
Regarding the way (my) 'body is built'.... It's been said that I walk like my dad; YEAH... so what, walking is walking, right? But then as I got older, more and more people said that they recognized me from afar simply by the way I walked. I have large bellied muscles, but I don't think that should have anything to do with my skeletal structure. Though I don't want to force my body to do anything that might put unwanted stressors on it, I want to use correct form and adjust it accordingly. So I gotta be careful not to rationalize 'bad form' until I figure out my limitations.
Thanks sooo much.
