Every athlete,from Tiger Woods(a golf player)to a high school quarterback(橄榄球赛中指挥反攻的四分卫),uses a form of self-hypnosis(自我催眠)to move their game to the next level Use the Olympics to 1earn how to use the amazing power of your subconscious(潜在意识)to do the same with your sport.

Here are some examples of how to best use the power of the mind:

During the 2004 Olympics,one of the swimmers told of how she would fall asleep each night with the picture of a clock in her mind. It was the timer’s clock she would see at the end of her Olympic swim and it always had her world-record-breaking time on it.

In his pre-shot routine, Tiger Woods never varies the number of practice swings or intensity of his concentration.The pre-shot routine is always the same so that the stroke will always be the same.

Michael Phelps,American Swimming Gold Medalist, always stretches out his back and arms by swinging both arms three times before his event. Not 2,not 4: always 3. He is anchoring(固定)in his winning state of mind and state of body as well as stretching.

In athletics, an anchor is a gesture or series of gestures that put you into the frame-of mind(and body)you want to be in to win.Repetition is what makes it work .That means practice,practice,practice ---- with your body as well as your mind.

Begin right now creating a ritual(固定程序)before you exercise.Visualize yourself doing whatever you do faster, longer, higher—whatever adverb works best for your particular activity. Then begin to mentally practice it. See or imagine yourself-----with your ideal body ---- doing your activity better, faster, longer, etc. Using both the power of your brain and the activity of your body, soon you will be better and fitter as you use the Olympics to help you create a happier and healthier you.
