Does that "extension" or "push" involve any actual muscular firing? I'm sure when people hear "extension" they might think to reach more physically (like straightening the arm). I'm assuming you mean to reach more mentally (so-to-speak), to the point that you really are reaching, without actually contracting any of the muscles? Or am I off base?
Adam, I mean actually pushing with the arm, lengthening it. Not a mental image.
