The best way to ensure proper hydration during workouts is to monitor fluid intake before, during, and after exercise. It’s recommended to drink water consistently throughout the day, aiming for about 17-20 ounces two to three hours prior to exercising. During workouts, aim to consume 7-10 ounces of water every 10-20 minutes, especially in high-intensity or prolonged sessions. Post-exercise, rehydrate with water or electrolyte-rich beverages to replenish lost fluids. Listening to your body's thirst cues and balancing fluid intake can optimize hydration and performance during workouts.
