6. If you hit fat shots, you're sliding your hips too much toward the target on your downswing. This causes your upper body to tilt away from the target so you can maintain balance. Now, the bottom of your swing arc is behind the ball you'll hit the ground first and the ball second.
FIX: Take your setup position and place a shaft straight into the ground just outside your left foot. From the top, your goal is to move your left hip and knee into the shaft at the same time and then turn them immediately to the left. If you slide, you'll hit the shaft and then bend it forward. This drill helps stabilize your lower body and position the bottom of your swing at the ball so you catch it flush instead of fat.
