A lot of amateur golfers do not practice on a driving range in any manner that will yield success on the range. First, your routing on the range should be the same routine you do on the course. You go to the range to practice and you should be practicing the exact same routine you do on the course on the range. Walk in, approach the ball, proper grip, stance, and lastly do not forget alignment.
On the range, you should ALWAYS pick a target. If you want to improve your game, the range is not for beating balls. Practice your swing, pick a target to work on your accuracy.
