I know, I know: Talking about how much water to drink can be b-o-r-i-n-g, and I bet you're tempted to skip right over this part. But I promise you, getting in the daily habit of drinking enough water is one of the easiest and most beneficial things you can do for your health.
Ask yourself this: How much water am I drinking every day? Throw out the old "eight glasses a day rule"—the new rule of thumb is to drink "half your body weight in ounces" a day, then add 20 ounces if you exercise.
For example, if you weigh 150 pounds, you'll want to drink 150 divided by two, which equals 75 ounces of water per day. Add 20 ounces for your workout, which brings your daily minimum recommended amount of water to 95 ounces per day.
If you're not one to measure, here's an easy way to find out: What color is your urine? Aim for a light straw color. You want your muscles sliding and gliding over each other, not getting "stuck" or stiff because of dehydration. Water removes waste products from working muscles, and when cells lose water, your body speeds up muscle and protein breakdown. Not good. Drink up!
