Draw a line two inches behind your ball and another one six inches behind your ball and practice entering the sand between those two lines
Each hand plays a specific part in the golf swing, the left hand controls the clubface for slicing and hooking and the right hand controls the clubhead for high and low trajectories
To create consistent aim with every shot in golf start with a constant positioning of your left foot one clubhead behind the ball, then spread out your feet depending on the club you are using
