Hydration plays a critical role in optimizing performance before, during, and after exercise. Adequate hydration before physical activity helps prepare the body for exertion and maintain blood volume. During exercise, staying hydrated is essential to regulate body temperature, prevent fatigue, and sustain performance. Post-exercise hydration aids in recovery, replenishing fluids lost through sweat. Maintaining hydration is vital across exercise types—its impact on energy levels and overall performance cannot be underestimated in any fitness regimen.
