Fitness is not just about the body; it also affects the mind. Regular physical activity has been proven to reduce symptoms of depression and anxiety, improve mood, boost self-esteem, and even enhance cognitive function. Exercise releases endorphins—chemicals in the brain that act as natural painkillers and mood elevators. Nutrition also plays a vital role in fitness. A balanced diet that includes carbohydrates, proteins, fats, vitamins, and minerals supports physical activity and recovery. Hydration is equally important, especially during and after exercise. https://www.fitnessison.com/
