How can a poor down flaw create bad shots?  I will explain various flaws in the down swing.

Bad Rhythm

Rhythm is the most important part of the golf swing.  When the rhythm is too fast, the result is always a poor golf shot.  The pause during the transition from back swing to down swing must be long enough to create a good golf shot.  If the pause is too short the rhythm will be too fast.  It is better to feel a longer pause than it is to feel a shorter pause.

Trying to Hit the Ball

This is the most common cause of a bad shot.  Golf is about making a motion towards a target and the ball gets in the way.  Any attempt to try to hit the ball or try to help the ball up into the air will always result in a poor golf shot.  The most natural thing to do is to try to hit the ball.  That is why golf is so challenging.  Very few golfers embrace the concept that golf is about developing a repeatable and efficient golf swing.  Golf is not about hitting the ball.

Doing Extra Motions with the Hand or Arms

This is what we are taught to do from the time we are young.  We are taught to do the extra credit problem in tests or to go the extra mile in all that we do.  In golf, the extra effort results in a poor golf shot.

My blog post, “Feel an Efficient Swing,” describes how critical the proper sequence of motions or Multiplication of Power is to making a good shot.  Good shots will result from a proper Multiplication of Power while poor shots will result from improper sequence of motions.

Finally, the Multiplication of Power should be the integral part of a rhythmic swing as I describe in my blog post, “How to Feel Rhythm.”

So the most common down swing flaws are a too short pause, trying to hit the ball, or trying to add extra motion.
