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.
How much water does one person need to drink per day? you should drink at least 7 to 10 average sized glasses of water each day.   One average sized glass is about eight ounces. There are 16 ounces in a pint, 2 pints in a quarâ¦t, and 4 quarts in a gallon, so, mathematically, there are about 128 ounces in a gallon.
