Physical Parameters Causing Flat Shoulder Plane and How to Diagnose Them:
In order to not flatten your shoulder plane during the golf swing several physical characteristics must be developed. First and foremost, the ability to separate your upper body from your lower body allows your shoulders to rotate around your spine without altering your original posture. Limited trunk to pelvis separation is usually caused by reduced spinal mobility and shortened lat flexibility. This separation is best be evaluated using the Seated Trunk Rotation Test, the Reach, Roll, and Lift Test, and the Lat (Shoulder Flexion) Test. Next, the ability to stabilize your spine angle during the swing is directly proportional to the strength and stability of your core musculature (your abs and glutes). When it comes to spinal stabilization the core is the king. These muscles help keep your trunk forward flexed throughout your golf swing. Core strength is best evaluated using the Pelvic Tilt Test, the Bridge w/ Leg Extension Test. Finally, in order to rotate around a stable posture one must have good flexibility in your hips and shoulders. This allows you to get the club into key positions without altering your spine angle. The overall flexibility of your hips and shoulders are best evaluated using the 90/90 Test, the Lat (Shoulder Flexion) Test and the Lower Quarter Rotation Test.
