Water is one of the best things you can put into your body, especially if you are big into fitness. Since most of our bodies are concentrated with fluids, we need a constant supply of water in order to maximize our potential in health. Furthermore, a neat fact concerning water is that if your body fluids drop only 5 percent, your energy loss will be up to as high as 30 percent according to dorchesterhealth.org. Water also helps in delivering oxygen throughout your body. The cardinal rule is for people to drink a gallon a day in order to maximize your health.
