PRGR "3rd Edition" Science Fit Textbook: Understanding the Swing Wall

I can't seem to break 100. My score has been in the 90s for years. I can't break 80 unless I'm in really good form. I think there are many people who are painfully aware of the barrier to their score. The barrier to their score is the barrier to their swing. Find out your swing level, overcome the barrier, and step up. This is a five-step guide based on three principles for achieving your ideal swing, and is targeted at all golfers, from beginners and intermediate players to advanced players who want to get closer to a professional swing.
