Loss of posture ultimately leads to several other swing faults such as flat shoulder plane, early extension, over the top and many other unwanted movements that lead to inconsistent contact.
HOW TO CHECK POSTURE
An easy way to check your posture in your upper body is by taking a video of your swing. Download the V1 Video Golf App (or anything similar) for your smart phone and have a friend stand behind you and video your swing from set up at address until you finish your swing.
Draw a line from your ear to your hip. If you swing the club to the top of the backswing and back down through impact the ideal swing keeps the line on your ear and hip. If you lose posture in your upper body, your ear will raise above the line. Losing your posture is typically the first of several swing faults that occur.
Let's take a look at three simple ways to maintain great posture in the golf swing...
#1 - START WITH CORRECT POSTURE
Setting up at address with the correct posture promotes the correct movement throughout the swing.
Players that set up too upright or bent over have problems creating the correct rotation. Neutral posture at address promotes the body to turn around the spine. Players hunched over at address restrict rotation while players too upright have a difficult time maintaining posture, create a flat shoulder plane at the top of the backswing and often over rotate.
Set up with approximately a 40 degree forward bend from your hips, also known as your spine angle.
As you swing the club, rotate your shoulders around your original spine angle.
Players that lose their posture stand up out of their posture and create a flat shoulder plane.
