That really fits for me-
the VHS video {old- William Hurt was the demo person} I found at the library on Alexander technique it had a lot of talking at first but when they finally demonstrated the way to find a proper head/shoulders position really was a help for me.
It also showed many other ways for better body uses.

also another tip- elongate the spine all the way to the top of the head - then tip chin down just a bit- no chin jutting forward allowed!
