The "Left Shoulder" Secret: Perfect Iron Compression Every Time
Giles Gill breaks down the 'left shoulder secret' for achieving perfect iron compression and low-point control. By shifting the left shoulder past where it started at address, golfers can move their swing's lowest point 3 to 4 inches past the ball for descending, ball-first contact. The video includes visual comparisons of Tiger Woods and Adam Scott along with three progressive drills using a club and towel.
To achieve ball-first contact, your swing's low point must be 3 to 4 inches past the golf ball and slightly below ground level.
Your left shoulder must shift past its starting address position by the time the shaft reaches parallel in the downswing.
Keep your chest relatively closed to the target while shifting forward to allow the club to shallow onto plane.
Place a towel a grip length behind the ball during practice to force a lateral weight shift and eliminate fat shots.
