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.
A common recommendation is to drink six or eight 8-ounce glasses of water or other fluid every day. But some adults may need more or less, depending on how healthy they are, how much they exercise, and how hot and dry the climate is. You may sometimes need to drink more water than usual if you: 1  Exercise intensely, especially in a hot climate. 2  Are sick, such as with the flu, or have a health problem like a urinary tract infection. 3  Are pregnant or breastfeeding.
