Definition: "Alignment" refers to the way a golfer positions himself relative to the golf ball - his feet, knees, hips and shoulders should all be lined up square (parallel) to the target line. Another way of putting it: "alignment" refers to a golfer's aim, and his body must be aligned properly to carry out that aim. A golfer can make the perfect swing, but if his alignment is off, the ball won't go where he wants it to. Poor alignment sometimes plays a role in creating slices or hooks; and - obviously - if your alignment has you pointing somewhere other than straight down the target line, you are less likely to hit the ball on that target line.
