Hydration is crucial for optimal workout performance. Even slight dehydration can lead to decreased strength, endurance, and cognitive function, affecting coordination and increasing fatigue. Proper hydration helps maintain optimal body temperature, muscle function, and nutrient transport. It’s recommended to consume fluids before, during, and after exercise, especially in hot or humid conditions. The type of exercise also dictates hydration needs; endurance athletes may require electrolyte-rich drinks, while others may need water alone. Staying hydrated can enhance recovery and overall effectiveness of workout sessions.
