Hydration Strategies: What to Drink Before, During, and After Exercise

Why is Proper Hydration Important for Athletes?

Proper hydration is essential for athletes as it affects nearly every aspect of physical performance. Water is crucial for maintaining blood volume, regulating body temperature, and allowing muscles to function properly. Even slight dehydration can impair performance, reduce endurance, increase the risk of heat-related illnesses, and hinder recovery. By understanding the importance of hydration and knowing what to drink before, during, and after exercise, athletes can optimize their performance and recovery.

What to Drink Before Exercise?

Hydrating Before Exercise: Proper hydration begins well before you start exercising. It’s recommended to drink about 16-20 ounces of water at least 2-3 hours before a workout to ensure your body is adequately hydrated. Additionally, consuming another 8-12 ounces of water 15-30 minutes before exercise can help top off your fluid levels.

Best Pre-Workout Beverages:

  • Water: Plain water is often sufficient for most workouts, particularly if they are less than an hour long.
  • Electrolyte Drinks: For workouts in hot and humid conditions or for athletes who sweat heavily, a beverage with added electrolytes can help maintain sodium, potassium, and other electrolyte levels.

What to Drink During Exercise?

Hydrating During Exercise: Maintaining hydration during exercise is crucial to prevent dehydration and maintain performance. Aim to drink about 7-10 ounces of water every 10-20 minutes during your workout. The exact amount can vary depending on the intensity and duration of the exercise, as well as environmental conditions.

Best Intra-Workout Beverages:

  • Water: For shorter, less intense workouts, water is typically sufficient.
  • Sports Drinks: For workouts lasting longer than an hour or high-intensity sessions, sports drinks can provide essential electrolytes and carbohydrates to help sustain energy levels and replace lost fluids. Look for drinks that contain a balance of electrolytes and around 6-8% carbohydrates.
  • Coconut Water: A natural alternative to sports drinks, coconut water provides electrolytes like potassium and magnesium without added sugars.

What to Drink After Exercise?

Hydrating After Exercise: Rehydration after exercise is vital for recovery and to replace the fluids lost through sweat. It’s recommended to drink 16-24 ounces of water for every pound of body weight lost during exercise. Weighing yourself before and after workouts can help determine your specific fluid replacement needs.

Best Post-Workout Beverages:

  • Water: For light to moderate workouts, water is often enough to rehydrate.
  • Electrolyte Drinks: For intense workouts or those in hot conditions, electrolyte drinks can help replenish lost electrolytes and support recovery.
  • Protein Shakes: Combining water or milk with protein powder can help with muscle repair and recovery while also providing hydration.
  • Chocolate Milk: A popular recovery drink, chocolate milk provides carbohydrates, protein, and electrolytes to support recovery and rehydration.

How to Create a Hydration Plan Tailored to Your Training Needs?

Assess Your Individual Needs: Each athlete’s hydration needs can vary based on factors such as body size, workout intensity, duration, and environmental conditions. Consider these factors when creating your hydration plan.

Monitor Your Hydration Status: Pay attention to signs of dehydration, such as dark urine, dizziness, headache, and excessive thirst. Using a hydration calculator or consulting with a sports nutritionist can help tailor your hydration strategy.

Adjust for Environmental Conditions: In hot and humid conditions, increase your fluid intake to account for increased sweat loss. Conversely, in cooler conditions, you may not need to drink as much.

Incorporate Hydration into Your Daily Routine: Maintain good hydration habits throughout the day, not just around your workouts. This can help ensure you start your workouts well-hydrated.

Listen to Your Body: Everyone’s hydration needs are different. Pay attention to how your body feels and adjust your fluid intake accordingly. If you’re consistently feeling fatigued or experiencing muscle cramps, you may need to increase your fluid intake.


Proper hydration is critical for athletes to maintain peak performance, prevent dehydration, and support recovery. By understanding what to drink before, during, and after exercise, athletes can create a tailored hydration plan that meets their individual needs. Incorporate a variety of beverages, such as water, electrolyte drinks, and protein shakes, to ensure optimal hydration and performance. Monitoring your hydration status and adjusting your fluid intake based on workout intensity and environmental conditions can help you stay hydrated and perform at your best. Always consult with a sports nutritionist or healthcare professional for personalized hydration advice tailored to your specific training regimen and needs.
