Performance Golf breaks down why amateur golfers 'stand up' or early extend during the downswing, leading to thin and inconsistent shots. Using the Trail Foot Back drill and a focus on shoulder rotation, the instructor demonstrates how to keep the right knee back and the right shoulder moving forward to maintain a consistent distance from the ground.
Standing up is caused by the trail knee kicking toward the ball while the upper body moves away.
Maintain your 'butt line' and 'head line' throughout the swing to keep a constant distance from the ground.
Pull your trail foot back so the toes are even with the middle of your lead foot to keep the trail leg from invading the space near the ball.
Ensure your trail shoulder works forward and passes the ball line by the time your arms are parallel in the follow-through.
Focus on getting the right knee to move toward the left knee rather than toward the ball.
