Three Days Away.
With the tournament a few days away, the important thing to focus on is to taper and not workout in the gym or play too hard tennis. You want to be as fresh as possible for the tournament. Sleep becomes a factor.
Two Days Away.
One last go at the courts, practicing and being sure all your shots work. Hydrate and sleep.
One Day Away.
This is a very important day. You must eat properly--have a nice meal and sleep. The meal should be light on beef. Chicken or fish go through the body fairly well, but beef will linger and make you feel heavy. Alcohol should be avoided.
For me, sleeping is so important nowadays. I must sleep at least seven hours to play efficiently.
