“While the average person should drink 400 ml of liquid during a regular exercise routine and 800 ml for competitive exercise (running or intense weight training), gentle exercises (such as a brisk walk) need a lot less,” says fitness expert Leena Mogre.
For professional athletes, however, the amount of water to be consumed is a lot more. They can find out how much water their body requires by weighing themselves before and after a workout. “During extremely intense workouts, it is possible for our bodies to lose half a pound or one. For every pound you lose, you should have 1,500 ml of water,” says Mogre.
