Loss of Posture
What is actually happening
You set an angle at address, and your swing was built to run on it. Then somewhere in the downswing, your body trades that angle for something that feels stronger. You stand taller than you started, or you dip lower. Either way, the swing arrives at the ball on a different track than the one it left on, and your hands have to make up the difference at the last instant.
What it costs you
Every inch of posture change has to be found again before impact, and hands under pressure miss. That's why your contact wanders all over the face. Heel, toe, thin, fat, on swings that feel identical. Consistency isn't a talent. It's a posture that doesn't move.
Your chest stays pointed at the ball until your trail arm straightens past impact. Bow to the ball at address, and hold the bow.
Club-Behind-Spine Check
Hold a club vertically against your back so it touches three points: the back of your head, the middle of your shoulder blades, and your tailbone. Keep all three touching while you hinge forward from your hips into address. That's a neutral spine over a real hip hinge, which is the posture your swing wants to keep. Now rehearse slow half swings without losing any of the three contact points. It should feel like almost nothing is happening, and that's exactly right, because a posture that holds doesn't produce sensations. Two minutes a day builds it. Once a week, film a swing down the line and lay a line along your spine at address. The line should still fit at impact.
