I was on golfwrx the other day and had a epiphany of sorts. I came across the Martinez "new concept for a golf swing" thread regarding bow to crossbow/etc.
Martinez explains that at takeaway he turns the upper arms CCW. To me this causes a limit for the BS and a tightness in the lead pectoral/shoulder muscles when the hands reach hip high.
Is this what loading PA4 initially feels like? What are the first PA you load?
The move possibly presets a limit to the load of PA3 which would inevitably keep PA2 loading on plane. Any input appreciated a this is my first post here on LB.
