[O.B.Left]

Here's what I consider to be Launching Pad..........like i said earlier but this is just me.......right shoulder kinda hangs back. Although 4B it would go through more.

You'd tend to think Arnie was 4B given all the effort etc but upon looking at this sequence? I dunno . Look at how little his right shoulder moves from frame 8 to Both Arms Straight, frame 10. Launching pad or what? So was his shoulder move in Startdown Motion or Work?

Did he load the Knuckle ?......no way especially given his "literally flat , geometrically arched" left Hand at Top. First joint index finger for sure Id say. But......

Maybe Yoda, who is a huge Arnie aficionado would have a more learned opinion. Actually I know he would.

This man was a King.
