In this video golf lesson, PGA Professional Jim McLean discusses a beneficial approach to the ball that involves going in shallow with a nice flat spot in the swing.
This approach is a key element of Lee Trevino's swing, and McLean offers an easy drag drill that will help you incorporate it into your own. It is a slow, easy practice swing that will help golfers break down the movement in order to correct alignment.
In the initial stance, the golf club will appear to be open, but as you go through the drill, it will eventually square up and release when going through.
Jim McLean demonstrates a swing drill to help you drive the ball straighter and longer.
