Highly successful golf swings are based on good fundamentals. These fundamentals are adopted through proper practice. It is not only the knowledge of basic golf fundamentals, it is the repeated application of them that produces consistent success. A very small percentage of golfers are ‘naturals’ and intuitively apply sound swing principals all the time. Hogan once said, “A natural golf swing produces bad results!” In other words, it takes practice to make a good motion - it does not come overnight.
Moreover, most novices or average golfers may practice but do so improperly. They either struggle with a misunderstanding of how the swing works thus grooving a consistenly incosistent motion, or try 'band-aids' and 'cure of the week fixes' experimenting so much that they never find a consistent move. Both cases are commonplace and yield little advancement.
Lets face it - golf is not easy. It is one of the most challenging games ever. So, it only makes sense that the learning process is developmental. Golf is learned in stages or building blocks. When stacking bricks, it would be rediculous to stack all the bricks at once. This would never work. Instead you must place one down at a time and move on to the next. Likewise in the golf swing, work on only one aspect at a time when conquering a new swing move. Follow the drills and exercises as suggested in practice plan. As tempting as it may be, do not try to add to this presciption. Doin so, will only open the doors for experimentation and failure. Stay the path and be patient, and results will be around the corner.
