One of the most common fears that I see with many students is that they are afraid of swaying on the backswing. Swaying occurs when the weight moves to the outside of the back foot on the backswing. Quite often, the result of this fear is that many players simply turn with the weight staying on the front foot as the club is swung back.
I believe it is essential to use the hips properly so the weight can turn and also shift weight to the back foot on the backswing. This promotes proper leg, foot and hip action throughout the swing.
The key to having a good hip action on the backswing is to move the left hip away from the target as the right hip turns in a barrel. This allows the weight to shift to the back foot without swaying. Please see the video for a full explanation.
