In America, one is not forced to join the military. Everyone volunteers to join the military but not all will be accepted. If the military recruitment finds out that you are underweight, overweight, have gene problems, or mentally unstable, you'll be sent home. Therefore, it's very important to have very good health to join the U.S. military. In order to have good health, you need to eat vegetables, fruits, meat, starch, and dairy every meal. It's very important to eat three meals a day and healthy snacks between meals. Healthy snacks are nuts, protein bars, protein shakes, etc. However, the most important thing to do to have good health is exercise. There are two types of exercises, weightlifting and doing cardio. Weightlifting allows you to build and tone muscles. Cardio allows you to burn lots of calories and increase your heart rate. Last but not least is sleeping. A night of good 8-hour sleep allows your body to rejuvenate and prevents feeling sluggish or cranky during waking time. These are ways to have good health before you join the U.S. military.
