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.
The rule of thumb is take your body weight, divide it by 2 (cut it in half), and that's how many ounces of water you should be drinking every day -- if you're active, you need to drink more. In your case, you need to drink about 92 ounces of water every day. That's a little more than 5 16-ounce glasses of water.
