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.
Weight: Multiply your weight by two-thirds. That number, in ounces, is the bare minimum amount of water you should be drinking. For example, a 160-pound person should drink at least 107 ounces a day. This might be different than your gender-based recommendation, and thatâs okay. Go with the highest amount.
