Hip Hinge

Hip hinge in the golf setup is the forward bend of the body at the hip joints. It creates the spine tilt that the golf swing needs. The hip joints are the ball-and-socket joints where the thigh bone (femur) meets the pelvis. A hip hinge is different from bending the spine, which produces C-posture, and from squatting, which produces too much knee flex. A proper hip hinge lets the spine stay straight while the upper body angles forward toward the ball. That is the foundation of an athletic, efficient golf posture that allows full rotation throughout the swing.

The hip hinge matters not only at setup but as a concept throughout the swing. "Keeping the spine angle" and "maintaining posture through the swing" are other names for maintaining the hip hinge set at address. It means the body stays in its bent-over position through the downswing instead of straightening up. Some golfers lose their hip hinge angle in the downswing, a fault called early extension. Their hips move toward the ball, which forces compensations in the arms and hands. Without those compensations, the club can no longer reach the ball from the original arc.

Developing a good hip hinge takes both mobility and strength. Hip flexor flexibility lets the hips hinge without the pelvis tilting backward (a posterior tilt that flattens the lower back). Glute and core strength then holds the hinge under the dynamic load of the swing. Golfers who cannot keep their hip hinge through the swing often have weak glutes. Those muscles cannot hold the position once the rotational demands of the downswing arrive. That is a physical limitation that technique instruction alone cannot overcome.
