When hitting full golf shots with a 7 iron ,should you always make a complete tilt/turn/extend backswing? If so what is the body feel?

Yes, your instruction about saying "Every full shot gets a complete tilt/turn/extend, regardless of the club" helps. I have become aware through the remote extended golf school of hard knocks that making a relaxed full/tilt backswing is a non-negotiable to launch the ball any distance. Without an S&T Golf Sensei on hand watching over old sore stiff me, my swing slowly degrades to appear as I have never had a golf club ever in my hand. Sometimes. Thanks 😫
