"Drink a couple of cups of water a few hours before you head out for exercise. Bring a water bottle with you and drink about ten big gulps from your water bottle every 15 minutes or so."
Be careful about this! Staying hydrated is important, but people shouldn't drink this much just to drink. Drink as you're thirsty. Drink every fifteen minutes perhaps, but not ten big gulps. Add electrolytes to the water! Well-hydrated people have still died from hyponatremia.
