This swing shows a solid basic setup but needs improvement in the right-leg movement during the backswing to create a more stable base and better timing, which in turn will eliminate early extension.
Root Cause
The right leg extends too much in the backswing, which leads to an unstable base and affects the body's rotation and timing in the downswing.
Priority Order
-
1
Lower Body (Backswing)
Your right leg (the one closest to the camera) straightens almost completely in the backswing. This reduces stability in the lower body and makes it hard to initiate the downswing correctly.
Maintain some flex in your right knee throughout the backswing. Feel that you rotate around your right hip without fully straightening the leg.
-
2
Lower Body (Downswing/Impact)
You show "early extension", where your hips thrust toward the ball during the downswing and you rise out of your posture. This is a compensation for problems earlier in the swing, often to create space for the club.
Focus on rotating your left hip back and away from the ball during the downswing, rather than pushing it forward. Maintain your hip hinge through impact.
Strengths
✓Your setup from the DTL angle is very good, with correct knee flex and hip hinge.
✓Your arms appear to stay in front of your body during the backswing, which is crucial for a good swing path.
Drill
Set up with a chair or wall just behind your butt. During the backswing, focus on keeping contact with the chair/wall with your butt, especially with your right glute, to prevent the right leg from straightening. Feel: "Keep contact with the wall behind you with your right glute during the backswing."
