When getting into a proper stance, cornerbacks should start by standing upright; feet spread shoulder-width apart. You should lean forward at the waist while stepping with your outside foot, bringing it forward and in, until it is lined up directly under your chin. In the beginning it is advisable to turn the front foot so that the outer edge of the foot is facing the line of scrimmage.
Next, bend your knees slightly, feeling most of your body weight on the front foot. Let your arms hang down in a relaxed manner with your head up, tilted slightly to the inside, looking at the ball. At this angle you can easily have the tight end and quarterback in your field of vision.
