One key focal point that I always work on with my students is to maintain the width and posture in their golf swings. Many golfers tend to stand up (lose their posture) during the backswing and / or the downswing, causing them to lose their angles and centre. Focusing on the backswing, this is usually caused by the golfer trying to create a wide backswing or trying to get the club way up there to create power…however, if you don’t have flexibility in your T-spine or Lats, then this becomes very difficult to get into that desired backswing position.
Here is a drill called Reverse Grip Extensions that is designed to give you the feeling of a short wide swing to keep you down in posture but maintain some width. What I want you to do is take your mid iron setup and reverse your grip, swing to the top of your backswing pushing the club away with your right arm (right handed golfer) and extending your left arm. Once you’ve done that a few times, go back to your regular grip and focus on that short wide backswing that will give you the feel of a full powerful turn without losing your posture and changing your angles. This drill will definitely help you feel extension in your backswing.
Have fun, Matt Truong
