Practice Level One
When starting to make a swing change, you are going to be learning new positions that are not as comfortable to your body. You will have to teach your body these new positions by stretching muscles and increasing flexibility. At the beginning, you will practice the correct repetitions without hitting a ball. This can be done away from the golf course if desired. It is possible that you may not need a club in this phase. Your body is learning a new system of motor skills. Make this level as simple as possible by avoiding anything that will distract the proper position.
In the early stages of a swing change, you are learning to use muscles in new positions. You may start using muscles that you never have before. Focus on learning these new positions before attempting to use them in a swing.
Practice Level Two
In the second level of practice, you will build from level one. You will start swinging the golf club working on your new positions. Again in this level, no golf balls should be hit.
Starting to swing the club will bring the new muscle positions into the golf swing. Hitting golf balls will only become a distraction at this level and should be avoided to achieve full efficiency.
Practice Level Three
Now it is time to start hitting balls. At the beginning of this level, get a small bucket of balls and spend more time than usual at the range. Take 5 swings without a ball, and then hit a shot. 5 without, hit a shot, and so on.
This will be tedious. However, you will be narrowing the gap between the swing changes and the golf shot. Stay disciplined at this level. Keep the proper cycle.
Practice Level Four
Full range practice. Time spent on the range hitting ball after ball enjoying your new swing change. At this level, you should not have to think about any type of mechanical movement, only the shots you plan to hit on the course.
Learning what your new swing is going to do on the golf course. What distances will you hit each shot and what direction will they go?
How good do you want to be?
Now you are on your way! Remember, anytime that you make any major change, you will need to start at the beginning of the cycle again.
