I start every lesson with a posture check. Many issues with the pivot or the plane and especially balance issues start with a setup position that’s out of whack.
From the down the line view I want to see the chest up, rear end out in a nice athletic position. The tips of your shoulders should be right over the tips of your shoes. This posture sets you up for a balanced golf swing.
Keep your head up. Don’t bury your chin in your chest. this just restricts your pivot and can cause too much arms swing or even lateral slide.Remember you get down to the ball with a slight flex of the knees not a roll over from your shoulders.From the face on view I would prefer for a right handed golfer the left hip to be slightly closer to the target than your shoulder. I prefer for the shoulders and hips to look as if they are running slightly up hill.The deal killer here is people who have their front hip lower than their back hip and have shoulders and hips which are running on different and converging lines.If you get postured correctly you are set up to make a great golf swing from the start
