Trajectory on your iron shots is achieved by hitting down on the back of the ball. Play the golf ball in the middle of your stance. Keep your grip pressure soft. Hinge your wrists early in your backswing. Keep your eye on the back of the golf ball and hit down on it! Don’t be afraid to make a divot, because good shots are impacted ball first, then the ground ground. The ground contact will be in front of the ball. Hitting down on the ball, by using your wrists and watching the back of the ball at impact makes the ball go launch upwards. Enjoy.
