At the top of your backswing, hold your shoulder and hips. This opens the gateway for the arms to fall to the inside portion of the golf ball on your downswing.
Make sure that your body doesn’t move forward on your downswing. Moving your hips too soon closes the gateway you created on the backswing and forces you to come “over the top”.
You should let your arms to release before your body. This allows the club to hit the inside portion of the golf ball. You will square up the golf club and you hit the draw every time.
