Water just doesn't seem to be something most of us think about on a daily basis. We get thirsty, we reach for something to drink - often what we choose to drink is a soft drink, or juice, or milk. What we need the most of is water. Unfortunately it is often the last thing we reach for.

You lose water through urination, perspiration and respiration. When you workout, you're going to lose even more water. If you don't drink enough water, you will become dehydrated and you won't perform as well as you're capable.

Many people think that they're drinking enough water just because they do not feel thirsty. However, this approach to water intake is a big mistake. Thirst is only a late indicator of dehydration, and it is possible that you will already be dehydrated by the time you're thirsty. So drink water on a regular basis.

On an off-day, you should drink eight glasses a day. You should double that amount when you work out, especially if you're training in a hot or humid climate.

Take a look at your uniform after your next class. Remember that sweat came from somewhere. Your body will take the water it needs from whatever it can. If you're not replacing those reserves with plain old water, just where is it coming from? Do yourself a favor. Start drinking all the water you need. Your body will thank you for it.
