Question: how long should you wait after drinking water to exercise?
Answer: To avoid that from happening in the first place, the American Council on Exercise recommends drinking 17 to 20 ounces of water two to three hours before a workout. Then, about 20 to 30 minutes beforehand, drink another 8 ounces. While exercising, continue to drink 7 to 10 ounces about every 10 to 20 minutes.
