You should drink two cups of water about two hours before you exercise. Dear Lifehacker, I've heard you need eight glasses of water every day, but I've also heard that it might be more or less. Some say too much water is bad, and many more say too little is bad.
This is your bare minimum water requirement â what your body needs to function. The basic equation for determining this is by dividing your body weight in half. So, if you weigh 200 pounds, you would need 100 ounces of water per day if you're not doing anything strenuous. If you're working out, hiking, at a high altitude or outdoors a great deal, you're going to need to add to those 100 ounces.
