The Weight Loss Challenge where I work is now in full swing. Last night was the first group fitness class offered by one of the other coaches. It was a big group and notable that many had not brought water with them. This is not a formula for success.
We hear a lot about keeping hydrated. We are not like camels who are able to store water for long periods and long distances. We use water to nourish our bodies and we lose water through sweating which helps to keep us cool. We must continually replenish. So what are the rules for water consumption with exercise?
Generall speaking the following guidelines apply:
- 2-3 cups of fluid 2 hours BEFORE the start of exercise
- 1 cup of fluid every 10-20 minutes DURING exercise
- 2-3 cups of fluid for every pound of body weight lost AFTER exercise
You’ll notice that I put “fluid” instead of “water.” Water is always excellent, but there are sports drinks that work as well. It is also better to drink something cool that something hot; this improves the speed of absorption. We also know that there are some liquids that actually accelerate dehydration: coffee and alcohol are two prime examples. This is not to say that you cannot have a glass of wine at dinner after exercising; just remember that this cannot be your primary form of hydration.
Dehydration is not pretty. It can lead to dizziness, loss of conscience, nausea and headaches. Bring a water bottle to the gym or to your class; this will help ensure that you are drinking enough.
Get your exercise on, but remember to get your hydration on as well!
