They are way too complex. Everything was explained in technical terms about the golf swing. This plane, this rotation, that axis, etc. You almost had to have a masters in physics to understand them.
They take way too much time. In all of these methods and books, you had to commit so much time to learning the steps, or the setup, or a particular sequence of moves, etc. Golfers said that they would rather be playing golf, not practicing all the time.
They are geared towards the better golfers. The methods and lessons weren't designed to be simple and easy for the golfers who most need the improvement. You needed to be a good golfer already just to be able to perform the drills, much less carry it to the golf course.
No way to put it all together. Most golf books just give you a series of drills or diagrams with no step by step instruction. You are left on your own to figure out how to apply the instruction.
It takes too long to see any progress. Whether you are taking lessons or using a program or book, it normally takes several weeks or even months to finally put it all together and start to see concrete results. And the truth is: most golfers have already given up by this point
It doesn't stick. And this is because they are making changes to your basic swing. Did you know that studies have shown that it takes 21 days of repetitive practice to ingrain just one small golf swing change? And it takes many, many changes to overhaul a golf swing.
