What is a good practice during exercise for hydration?

Drinking 16 fl oz before and 8 fl oz every 20 minutes during exercise is considered an effective hydration strategy because it ensures that the body maintains adequate fluid levels throughout the duration of the physical activity. Proper hydration is crucial to prevent dehydration, maintain performance, and support overall bodily functions during exercise.

By consuming a substantial amount of fluid before starting the workout, you set a solid baseline for hydration, which helps in regulating body temperature and optimizing muscle function. The guideline to drink 8 fl oz every 20 minutes ensures that you are regularly replenishing fluids lost through sweat without overwhelming the stomach, which could lead to discomfort.

This proactive hydration strategy aids in sustaining energy levels and enhances endurance, making it more beneficial compared to simply drinking when thirsty or at the end of exercise, as those methods might lead to inadequate hydration if thirst does not arise or if fluids are not consumed often enough.
