Hi. I have been playing on and off for about 20 years and could never really get my handicap down. Swing was too fast, stance not great etc. Got loads of coaching manuals and instruction but never really clicked. I gave the content of the attached link a go and it seems to be working. Dropped a couple of strokes on the handicap in 3 months. Have a look and see what you think. Good Luck.
