Before, during and after exercise
Drinking plenty of water is important, particularly among people who exercise vigorously.
The American Council on Fitness offers these recommendations for how much to drink:
- Two or three hours before you start to exercise, drink 17-to-20 ounces of water.
- Twenty to 30 minutes prior to exercise, or while you’re warming up, drink another eight ounces.
- While you’re exercising, drink seven-to-10 ounces every 10 minutes to 20 minutes.
- Within 30 minutes of completing your workout, make sure you drink another eight ounces.
