Master the Setup
You may not be able to replicate the swing of a tour professional, but you can master the fundamentals of a good setup.
These fundamentals are often called statics because you can replicate them without any movement.
Grip, stance, alignment, and posture are fundamentals that you can master.
Look at photos and videos of a professional whose swing you admire.
Use a full-length mirror and then later have someone take a video of you.
In this way, you can copy these fundamentals for yourself.
These positions will help you to swing the club better and make better contact without moving anything.
It may take awhile for you to feel comfortable with the changes.
Ask your pro to guide you in developing a good setup, and you will be on your way to a big improvement.
