Those are cues which work well, but can sound like Elvish to many trainees, particularly when they're new to deadlifting. Instead, get more acquainted with external cues which, contrast to their internal counterparts (which speak to what the body is doing in space), imply intent or direction.
These can be game changers when it comes to helping people better understand what you're asking them to do as a coach.
One of my favorite books is A Book Of Five Rings by Miyomato Musashi. Musashi was a badass 17th century Japanese swordsman who never lost a duel in over sixty fights. This book outlines his philosophy of success. I re-read it recently and was amazed by how many of his principles apply to a variety of areas in life, including productive strength training.
