I have had so many people both on the range and in online lessons have the same problem, I thought I would revisit this video that has become my most viewed.
People turn their shoulders too flat going back and get too vertical coming down.
Either by necessity to hit the ball, or as a result of getting too inside, lifting the arms late and being forced to drop the right shoulder too much to come from the inside.
The left shoulder needs to work down and out in the backswing in order to keep your spine angle relatively constant in the down the line two dimensionally.
…and your right shoulder needs to work down and out in order to keep the spine angle constant on the downswing.
The dissenters will say that’s over the top on the downswing, but that’s only if you lack tilt away from the target.
1. Have SOME spine tilt away from the target throughout the swing.
2. If you hold a shaft in front of your shoulders at address. Keep that shaft perpendicular to your spine and that’s the angle you want your shoulders to move. Left shoulder down and out in the backswing, right shoulder down and out in the downswing.
