Take the superb performances witnessed in junior golfers like the Song sisters, Ty Tyron and Michelle Wie. The amazingly high level of performance of these very young junior golfers has often been discussed. Several theories and reasons have been brought forward. Most of them are not true. For example a common belief is that these younger golfers perform better and respond better to golf swing basics taught because of their flexibility. This is absolutely NOT TRUE.
The difference between junior golfers and adults is usually strength and not flexibility. I have personally worked with hundreds of junior golfers and I have watched in amazement as a very short period of time of doing strength exercises has yielded increases in their golf drives of as much as a whole 50 yards.
However a quick word of caution. Participating in the wrong strength training exercise programs can damage a golfer instead of improving their game.
My work with junior golfers has practically proved something to me beyond any reasonable doubt. And that is the fact that training in the correct golf swing basics at the same time that somebody is doing the right golf-specific exercises, is a very powerful way of developing and improving anybodys game.
Without exercise the best training in the world on golf swing basics will have NO impact at all.
