The correct initiation of the downswing is crucial as it helps prevent the out-side-in problem and serves as the foundation for an effective swing and strike.
The first sensation when starting the downswing should be the outward rotation of the left knee. Combined with proper weight transfer, the spine will naturally shift from a leftward tilt to the necessary rightward tilt.
During the impact phase, ensure full weight transfer first, then straighten the left leg, drop the right shoulder, and generate power to strike the ball.
