Under normal circumstances, eight ounces should be enough water to meet your needs as far as bodily functions go.  But there are also a few external factors that need to be taken into consideration in regards to your fluid replacement – hot weather, humidity, your training length and intensity, and if you are training outdoors or indoors (especially if you are competing in different conditions than what you are used to). If you train regularly in such conditions, you have to change your hydration strategy to accommodate those circumstances.

A good measure of hydration is the color of your urine. If you are drinking enough water during the day, your urine should be a pale-yellow to clear color. If it’s darker than pale yellow, than that is usually a sign that you are dehydrated.

Looking for a more scientific way to figure out if you need to be drinking more water? Here’s a simple way to calculate your sweat rate. When exercising in the heat or following an intense or multi-session training program, one of the first things we recommend you doing is a sweat rate test so that you can figure out a precise calculation for your fluid replacement. Here’s how:

  1. Weigh yourself before a workout.
  2. Weigh yourself after the workout.
  3. Calculate the weight change – that is how much water you lost.
  4. Drink 16oz. water for every pound lost.

Electrolytes

Sometimes water isn’t enough – or it might be too much. If you start to feel bloated, then it may be a sign that you are drinking too much and you may need to supplement it with some electrolytes (sodium and potassium) so that it helps your muscles retain and use energy when you need it. If it’s hot and/or you sweat a lot, chances are you need to incorporate these anyway. If you are low on electrolytes, you might feel sluggish, nauseated or have a headache, or you might not have any symptoms – it’s best to stay on top of it when you know the external risk factors are high. Here are some options: You can add a pinch of colored salt to your water or add electrolytes using a product like Advocare Rehydrate. If your goal is focused around fat loss, we recommend avoiding any “sports drinks” such as Gatorade or Powerade due to their high sugar content.
