Before, during, and after a workout it’s important to drink plenty of water. Staying hydrated means that you get the most out of your workout. Sweating allows the body to lose water and electrolytes. Drinking water before, during, and after a workout helps with successfully recovering from your fitness training. The amount of water needed after a workout depends on the type of exercise completed, how much sweat was lost and other factors. As general rule, drink as much as you can handle.
