IRON CLAD FUNDAMENTAL NO. 2:  ALWAYS SET UP AT ADDRESS WITH NEAR PERFECT POSTURE

This is another iron clad fundamental you can master, do consistently and control as well as any pro. This is to have perfect or near perfect posture at address.  

So how do you do it?  The answer is CUBOAH.  Stand to the ball with your 

1.  Chin Up

2.  Butt out

3.  Arms Hanging.

1.  Chin up:  This keeps you from slumping over the ball.  You need a straight back and keeping your chin up helds a lot.

2. Butt Out:  You bend over slightly at address by sticking your butt out and slighly flexing your knees.  Again this will keep your spine and back straight.  

3.  Arms Hang:  People get very confused about how close or far they should stand away from the ball.  All you have to do is close your eyes, have your butt protruding behind you so that you bend slightly over with a straight back, and your arms should loosely hang down from there. That is all you need to do.  It puts your hands about 4" to 5" away from your legs.  Letting your arms hang naturally results in you neither reaching for the ball or standing too crowded into the ball.  

Do these three steps and you will have all the posture you will need to make a good golf swing.
