This is especially important during exercise, when you will lose water naturally through sweat.Drinking water also helps your body burn stored fat. If you're not drinking enough water, your liver will be forced to help your kidneys detoxify your body.Another benefit of drinking water is that it makes your muscles stronger.Drinking plenty of water enables your muscles to work harder and longer before they feel tired, and this can help you build muscle.One of the lesser known benefits of drinking water is that it helps keep your joints strong, healthy and lubricated. Your joints need moisture in order to remain strong and flexible, so that your movements are smooth and pain free during exercise.
