|Reverse Spin Angle|
A Reverse Spine Angle is any excessive upper body backward bend or excessive left lateral (for right handed golfers) upper body bend during the backswing. Essentially it is when your spine/head is angled toward your target during the backswing. This swing characteristic makes it difficult to start the downswing in the proper sequence, because the lower body is in a position that usually limits its ability to initiate the downswing. The upper body tends to dominate the swing when the lower body can’t start the downswing or has a limited ability to initiate the movement. The upper body domination will eventually create path problems and limited power output. This swing characteristic also puts excessive tension on the lower back due to forced inhibition of the abdominal musculature during the backswing and is the leading cause of low back pain in golfers.
The easiest way to diagnose a reverse spine angle is to use the spine angle line at the top of the backswing from the face-on camera view. Advance the video to the top of the backswing. Draw a line from the middle of the head to the middle of the waist. The line is called the spine angle line. If you are looking from the bottom of the line to the top, it should point away from the target. If the spine angle line is pointing towards the target (even just a little bit), then you have a reverse spine angle.
Several physical characteristics must be developed in order to maintain your spine angle during the backswing.
