how much water to drink for endurance

To ensure optimal hydration for endurance, there are several strategies recommended by experts like Andrew Huberman and Andy Galpin on the Huberman Lab.

1. Daily Hydration: A simple guideline is to drink half your body weight in ounces of water per day. For example, if you weigh 200 pounds, aim for 100 ounces of water daily. This serves as a baseline for most people 1.

2. During Exercise: Use the "Galpin Equation" for hydration during exercise: divide your body weight in pounds by 30 to get the amount of ounces to consume every 15 minutes of exercise. For instance, a 180-pound person would need 6 ounces every 15 minutes 2.

3. Post-Exercise: After a workout, it's advised to replenish 125% to 150% of the weight lost during exercise in the form of fluid. For example, if you lose 2 pounds during exercise, you should drink about 2.5 to 3 pounds (approximately 40-48 ounces) of water post-exercise 1.

4. Electrolytes: Ensure you're also consuming electrolytes such as sodium, potassium, and magnesium, especially if you sweat heavily. These help in maintaining cellular function and preventing issues like cramps 3.
