I hear in golf, balance is the fundamental principle one needs to most consistently observe. Keeping ones eyes on the ball and executing the correct posture and stance that will allow oneself to see the ball during the stroke and at every second while striking the ball is secondary. Making the time to develop ones own personal method and technique is third. Finding and implementing a stretch and warm-up (or down) routine before and after practicing or playing a round of golf could be an added bonus. Bringing snacks and water is a must since a round of golf could take a number of hours to complete.
When fixing a swing flaw, never practice perfect. The correcting action or move must always be exaggerated on the practice range to affect your internal programming. Then take it to the first tee and just play,forget about the drill. Fairways and greens
While practicing my takeaway and back swing one afternoon about six months ago I noticed that by squeezing the bicep of my arm closest to the target (my target arm) against my pectoral chest muscle, minimized my margin of error on back swing and promoted solid ball contact and increased my accuracy with my swing. But I wasn't sure why. Yesterday while surfing the web I found a video on youtube entitled "Plane Drill" by Jeff Ritter that clearly articulated the same concept. He noted that by squeezing the logo on the front of your shirt with you arm on your and back swing and through swing created very similar results. Take a look.
Swing short. Take the club back no further than 45 degrees with wedges and no further than parallel with the driver to promote connection and accuracy.
I was speaking with two fellow golfers at the golf course last week and the topic of Speed Golf came up. Robert did some research and shared this wikipedia link with me. "Take a look. It looks like it could be fun". Thanks Robert. http://en.wikipedia.org/wiki/Speed_golf
