There is some confusion concerning Imagery and Visualization and we need to deal with this to start with. It is only in recent years that more emphasis has been placed on the mental side of tennis together with other sports, even though tennis is 65% mental once you have got past the learning of techniques, tactics etc. Visualization has been used for some time in certain sports but this is only part of the equation and only refers to the practice of mental rehearsal with the emphasis on the visual sense, to imagine a sport situation. Tennis players use visualization on a daily basis when getting ready for the serve, whilst doing their preliminary routines they are visualizing in their minds where they are going to place the serve. This can be very powerful and should not be overlooked as a help to your serving practice.
