Create a draw shot
Take a tennis racket and make a backward movement with your right arm travelling around your body. Try to rotate the tennis racket so that it is open to the target.
Then start to move your weight back to your left side rotating your right arm back anti-clockwise to impact.
Continue to rotate your arm and body through to face your target.
Now set up with your golf club.
Create a similar feeling to the drill with your left shoulder turning, your arms rotating clockwise and your wrists setting in the backswing.
Then start to unwind feeling the forearm rotation squaring and closing your clubface. This movement should create a draw shape moving the ball from right to left in flight. This is similar to a forearm topspin shot in tennis.
