Hip Hinge
The hip hinge is bending forward from the hip joints (not the waist) to establish the correct spine angle at address. It is the foundation of athletic posture in golf.
Hip hinge in the golf setup is the forward bend of the body at the hip joints (the ball-and-socket joints where the femur meets the pelvis) that creates the spine tilt necessary for the golf swing. It is distinct from bending the spine (which produces C-posture) and from squatting (which produces excessive knee flex). A proper hip hinge allows the spine to remain straight. At the same time, the upper body angles forward toward the ball. This means creating the foundation of an athletic, efficient golf posture that enables full rotation throughout the swing.
The hip hinge is important not only for setup but as a concept throughout the swing. Maintaining the hip hinge established at address (also described as "keeping the spine angle" or "maintaining posture through the swing") means the body stays in its bent-over position through the downswing rather than straightening up. Golfers who lose their hip hinge angle through the downswing (early extension) bring the hips toward the ball and force compensations in the arms and hands. This is. This is because the club can no longer reach the ball from the original arc without those compensations.
Developing a good hip hinge requires both mobility and strength. Hip flexor flexibility allows the hips to hinge without the pelvis posteriorly tilting (flattening the lower back), and glute and core strength maintains the hinge under the dynamic load of the swing. Golfers who cannot maintain their hip hinge through the swing often have weak glutes that cannot hold the position when the rotational demands of the downswing are applied. This means a physical limitation that technique instruction alone cannot overcome.
Practice the hip hinge as a separate exercise. This means stand 6 inches from a wall, then push your hips backward until they touch the wall. At the same time, keeping your spine straight and your knees only slightly bent. This is the hip hinge. This means the feeling of hips going back and spine going forward. This means and it translates directly to golf posture when you repeat it with a club.
Test your hip hinge capacity with a dowel rod. This means hold a dowel along your spine touching your head, mid-back, and tailbone, then hinge forward from your hips. This means at a correct golf setup angle, the dowel should maintain contact at all three points. If the lower back arches away from the dowel (anterior tilt / loss of lower back contact), your hip flexors are limiting the hinge. If the mid-back arches away (C-posture), your thoracic mobility is the limiting factor.
Example
Placing a club along the spine. At the same time, bending forward should show the spine staying straight, the hips pushing backward. The knees flexing slightly. This means the hip hinge pattern.
How it shows up on video
From a down-the-line camera angle, the hip hinge is directly visible at address as the forward angle of the spine from the hips toward the ball. This means about 25–45° from vertical depending on club length. A proper hinge shows a straight spine with the angle originating clearly at the hip joints, not from a curved lower back. During the swing, hip hinge maintenance is visible from down-the-line as the spine angle staying consistent between address and impact, with early extension showing as the hips moving toward the ball and the spine angle decreasing.
Common mistakes
- Bending the spine rather than hinging from the hips. This means a spine-bend (C-posture) restricts rotation and is a structural limitation that will cost both flexibility and consistency throughout the swing.
- Confusing hip hinge with squatting. This means pushing the hips back during a hip hinge is correct. Pushing the knees forward (squatting) is different and should not be the primary movement. In a hip hinge, the hips go backward while the spine goes forward.
- Losing the hip hinge at the start of the downswing (early extension). This means straightening up from the hip hinge at impact is one of the most common and consequential setup/swing faults. Physical training to strengthen the glutes in the hinged position directly addresses this.
- Using a hip hinge that is too deep or too shallow for the club — the correct hinge angle varies by club length. Hitting a driver from a deep hip hinge (wedge address angle) requires compensations to make solid contact, and vice versa.
In SwingVantage Motion Lab
SwingVantage measures hip hinge quality from down-the-line video by estimating the spine angle at address and comparing it to the spine angle at impact. The system can identify insufficient hinge (too upright), excessive hinge (too bent), and loss of hinge (early extension) through the swing. These observations are most reliable from a clearly positioned down-the-line camera that captures the full body from feet to head.
Related terms
- PosturePosture in golf is the spine angle at address. This means bending forward from the hips with a straight back. As a result, the arms hang freely under the shoulders and the body can rotate athletically.
- Knee FlexKnee flex at address is the slight bend in the knees that creates an athletic, ready posture. This means enough to feel springy and stable, not. As a result, much that it restricts hip rotation.
- Early ExtensionEarly extension is thrusting the hips toward the ball during the downswing. This causes the golfer to stand up out of posture and forces compensations at impact.
