On the whole I prefer the Rick McKinny approach. The problem is not that you should be using the back muscles (this itself is largely irelevant the bow doesn't know or care if you're using "back tension" or not). Rather you need to minimise tension in the bow hand and the draw hand and minimise tension in the drawing arm. (Lee's bicycle chain). Alignment etc. then automatically follow. So initially forget the back and just relax the arms/wrist/fingers.

The only complication arises with how go through the clicker. Which ever side of the push - pull pendulum you prefer control of the shoulder assemblies then does come into the frame.

Low poundage bow, bungee or theraband is the way to get feel and control of expansion. I also use a loop of string between bow string and elbow ( the poor man's formaster).

May be worth mentioning the RM trick. Raise the draw arm horizontal level with and line with the shoulders. Bend the elbow (horizontally) to maximum. Rotate the draw arm to bring the draw fingers to the chin (elbow comes out). Then rotate the draw arm by scapula movement (not biceps!) to bring the draw elbow in line with the shoulders while keeping the fingers contacting the chin.
