The Inner Game of tennis is that which takes place in our mind, played against such elusive opponents as nervousness, self-doubt and lapses of concentration. It is a game played by our mind against its own bad habits. Replacing one pattern of behaviour with a new, more positive one is the purpose of the ''Inner Game''. Peak performance at tennis, like any sport, only comes when our mind is so focused that it is still and at one with what our body is doing. The key to the ''Inner Game'' and better tennis is achieving this state of relaxed concentration so that we are playing ''out of our mind'' and therefore no worrying about how, when or where to hit the ball. In The Inner Game of Tennis, Tim Gallwey, a professional player and instructor who has produced dramatic results among the amateurs and pros he has trained, explores how to overcome mental obstacles, improve concentration and reduce anxiety for better performance at every level. There is no physical reason why any of us should not more consistently serve aces or hit perfect returns. The Inner Games approach makes all the difference.
