Staying hydrated
When we exercise, it's that much more important that we drink enough water. But hold on a second - just how much constitutes enough? For one, a simple rule to go by is that if you're thirsty, you've already waited too long. Your initial signs of thirst are a relatively benign indicator that you're already slightly dehydrated. However, in case you're not really into simple rules, Women's Health magazine published a handy article that spells out just about how much water you lose (and, therefore, how much you will need to replace) for a variety of physical activities.1 1/2 hours of Singles Tennis: 25 ounces of water lost
