In the firing sequence of a golf swing, which part reaches the backswing first?

In the firing sequence of a golf swing, the pelvis is the first part to reach the top of the backswing. This is crucial because the pelvis' movement sets the foundation for a proper swing sequence. The pelvis initiates the turn and creates a stable base, allowing the upper body, including the thorax, arms, and club, to follow in a coordinated manner. When the pelvis rotates correctly, it generates the necessary torque and power, which helps position the rest of the body for an effective transition into the downswing. This coordination between the pelvis and the upper body is essential for a solid body-swing connection, emphasizing the importance of proper sequencing in the swing mechanics.
