1. Find out your weight.

The old adage was that you should drink 8 glasses of water a day but experts are beginning to give different advice. Experts now advise that each person should drink the right amount of water for their body weight.

This means that you first need to know how much you weigh. Doing this will help you determine the right amount of water intake for your body.

Of course this makes sense on even the most basic level right? Someone who weighs 100 pounds will have different hydration needs to someone who weighs 250 pounds. So in order to properly determine the right amount of water you must know your exact weight. Once you know your weight then do the following:

2. Exact daily water intake calculation… in 2 easy steps:

Once you know how much you weigh, you only have 2 steps to calculate your exact daily water intake.

  1. Divide your weight in half and convert it into pounds.
  2. Divide that figure (in pounds) by half to get your daily water intake in ounces.

For example, your weight is 100 pounds, divide that by 2, which gives you 50 ounces (oz). This means you should be drinking 50 oz (or 1.42 liters) each day.

If you are using the simple calculation used in this post to work out how much water you need to drink a day remember work outs.

You must compensate for the water that you lose when you are physically active.
