Swing set up
Should I keep my left arm completely straight when hitting the ball and how far should I stand from the ball at set- up.
The left arm cannot completely straighten, the best you can get is about a 7 degree angle. You may think about your left arm hanging long, but not tense under your shoulders at address. You may think about your left arm getting wide on the backswing, but I would never use the word straight. On the throughswing, it rotates, stays soft, then lengthens. It is very common for right handed golfers to put too much tension and importance in the left arm. Take the pressure off the left and pay more attention to the golfswing being right sided, not left sided. Let me know if this answers your question.
