Water and Exercise
Unless you’re an elite athlete, water is the best way to replenish fluids lost in exercise. Sports drinks are made to replenish lost electrolytes and provide added carbohydrates to fuel athletes after prolonged vigorous exercise. Everyday moderate exercise of 30 to 40 minutes does not qualify.
Thirty minutes before you go out for your daily routine, drink one to two cups of water. Throughout your exercise, drink a half to one cup of water every 10 to 15 minutes.
When you’re done, replenish your fluids by slowly drinking water over the next several hours. To adequately rehydrate, you should consume two cups of water for every pound lost during exercise.
