How long should you take off before pt test?

Someone on military.com asked this question already...here's the answer from their site directly:

One Day Prior to the PFT Should be a Day Off

Take a light walk, run or bike for 15-20 minutes with an equal amount of time spent of stretching. The night prior to the test should be spent relaxing and eating foods high in protein and carbohydrates such as pastas, green leafy lettuce, spinach, fish, chicken, lean meats. Lay off high fat foods. Drink water all day long.
