Tempo is the most misunderstood word in golf. Most golfers think the word means slow. That is not the case, tempo is nothing more than a smooth transition between the back-swing and the downswing.
For example: if your total swing time is two seconds, the back-swing time should be one second, the downswing should be one second. The time factor should be split 50/50. I like to tell my students that we are trying to fool mother physics. Take the club up and down without the club knowing it changed directions.
I have been asked many times, what is the standard time for most golfers? My answer is always the same: 'There is no recommended time." Everyone must work with what tempo works best for them. I have seen tempos range from .065 seconds to as much as 3.5 seconds.
Many golf swings have been destroyed by trying to slow his/her swing down. Not to say some golfers shouldn't slow their swing; however, others would improve if they'd speed up their backswing. I have found if the total swing time is under 1.5 seconds, one must speed up the backswing to match the downswing. With a quick tempo type swing, slowing down the backswing will do more harm than good. Remember, we want to encourage a smooth transition between up and down. Slowing the backswing down just creates a bigger differential between the backswing and the downswing. The downswing seems to be more difficult to control; therefore, try to speed up your backswing to even out the two.
Controlling tempo is much easier with a slower swing (over 1.5 seconds) versus a faster swing (under 1.5 seconds). It is very difficult to judge time when it involves any time under 1.5 seconds.
Count million one, million two, etc. while taking a practice swing. This will give you an idea how fast or slow your total swing time is. Then experiment with your tempo, trying to match the backswing and downswing time.
Think of tempo as a time span, a motion that is constant with all shots, regardless if it is a putt or a drive. Similar to child's swing, swinging back and forth.
