PGA instructor Aimee Cho demonstrates the 'Hulk Leg Drill' to stop early extension in the golf swing. By placing an elevated balance board under the lead foot, golfers learn to keep their lead knee flexed, maintain spine angle, and create dynamic lower body rotation through impact. The drill reinforces proper weight shift and prevents the hips from thrusting toward the ball.
Early extension happens when hips thrust toward the ball and the spine angle stands up, causing power loss and contact issues.
Elevating your lead foot on a soft balance pad deepens lead knee flex and hip bend, making it easier to keep your posture.
Focus on keeping your lead knee bent and pointing forward throughout the backswing and half-swing finish.
Maintain pressure into the lead balance board through impact to automatically improve weight shift and minimize early casting.
