During-Workout Hydration Tips

Use these tips for optimal hydration during exercise.

  • Drink every 20 minutes: Regular fluid intake during exercise maintains performance
  • Small amounts frequently: 150-250ml every 15-20min better than large amounts
  • Use sports drinks: Carbs + electrolytes during exercise lasting >60min
  • Don’t wait for thirst: Drink early during exercise when not thirsty yet
  • Cool drinks help: Cooler beverages encourage more during-exercise fluid intake
  • Climate matters: Hot weather requires more fluid during workout
  • Adjust for sweat rate: Heavy sweaters need more during-exercise hydration
