Get a good night's sleep before the day of the physical fitness test (PFT).
Eat a good evening meal and drink lots of liquids (NO ALCOHOL).
Eat a good breakfast if you have at least 3-4 hours before the test. If not, drink some water. If you drink coffee, one cup is all right but NO MORE.
If you smoke, give it up (preferably for good) at least 12 hours prior to the test.
Let OUT air when you come up in the sit-up or go up in the push-up. Breathe IN when you go down in the sit-up or go down in the push-up. DO NOT HOLD YOUR BREATH.
When running, breathe naturally and deeply! DO NOT take quick, shallow breaths. YOU NEED AIR TO RUN 2 MILES.
If you have a break between events, WALK around; DO NOT lie down. Lying down or remaining inactive may make your next event HARDER. By walking around, your body will recover more rapidly.
As in any competition, tell yourself that you are a winner, that you CAN do it, and that you CAN DO BETTER THAN EVER!
