A few years ago I came across Tiger Woods’s five swing pointers. I should have saved the reference, but I didn’t. Anyway, I present them to you with my commentary.

Tiger: I turn my shoulders as far as possible without letting the range of motion disrupt my spine angle or the position of my right leg.
TRG: Complete your backswing. Keep the position and flex of the right leg fixed.

Tiger: I make my shoulders and arms work together throughout the swing. I don’t let one get too far ahead of behind the other. That is one of the secrets of good rhythm and tempo.
TRG: Also for hitting the ball where you intend.

Tiger: I keep the clubface square throughout the swing. That means the clubface is parallel with the left wrist and forearm.
TRG: How do you do that if all of that is behind your head and you can’t see them? You feel it. If you try it, you’ll find out it’s not that hard to do.

Tiger: I strive to get the sequence of motion on the downswing just right. My lower body leads the way, followed by my shoulders, arms, and hands.
TRG: Many good golfers start their lower body forward before their upper body has finished the backswing. That’s a good move if you can do it. Otherwise, see point #2.

Tiger: I hit through the ball, not at it. I want to keep the clubhead traveling fairly low to the ground for a brief period after impact. That thought will promote solid contact, accuracy and maximum distance.
TRG: The first sentence is how impact is done: hit(or swing) through the ball, not hit at. (Putt that way, too.) Keep the club low after impact to drive the ball forward. The loft of the club and its trajectory at the ball take care of getting it in the air.
