There are some advantages and disadvantages to having a simple golf swing. If it is not technically complicated then there is no so much to concentrate on when you swing and less elements for you to make mistakes in.
However, a simple golf swing may not be the best type, despite many people claiming that it is. A lot of the evidence does point towards it being more accurate and more consistent so therefore it would seem that it would be the best swing to use, especially perhaps for the beginner. The technique means that you move fewer body parts during the swing which means there is less chance of injury and the movement is not so complicated.
