How can you improve your back swing?

you should start the backswing by swinging your arms back with no thought of your shoulders turning. Avoid trying to turn your shoulders at the start if you do you will chunk. let the shoulders move once your arms are past your right leg

The answer above is one of the worst things you can do! You have to ONLY THINK OF YOU SHOULDERS TURNING BACK, LET YOUR ARMS GO BACK NATURALLY. You should never worry about your arms in a back swing because if you do then your going to shank it A LOT. If you want to learn more about the swing I'm talking about type in this question in wiki answers.

"What is the correct golf swing plane?"

This will tell you everything you need to know; the arms and hands jobs is to only hold on to the club but the BODY does EVERYTHING. Contact me if you have any questions about this.

I totally agree 110% with FutureLPGAgolfer on this one. The 'grandfather of golf instruction', John Jacobs, to whom David Leadbetter, Butch Harmon and other modern day gurus pay great respect, summed up the essence of the golf swing as follows:

Backswing: Turn the shoulders, swing the arms, cock the wrists.

Down and through swing: Turn the hips, swing the arms down, uncock the wrists.

The above, done rhythmically, is the essence of the swing. No words sum up the swing better than those.

You want the arms and golf club to start their movement back before the shoulders start turning. The club head has a much longer distance to travel to the top of the back swing then do the shoulder's If you start turning the shoulders with the club, hands and arms you won't have anywhere for them to go once the shoulders have reached their max turn(without a lift to the top). Once the club, hands and arms reached your knee's (or so) then it's time for the shoulders to catch up and start turning to the top. And also, don't listen to anyone who hasn't broke 70 for 18 holes and go see a Golf Professional for real help.
