Which of the following is a benefit of moderate exercise?

Moderate exercise is associated with numerous health benefits, and increased energy levels is a prominent one. Engaging in physical activity facilitates better oxygen circulation throughout the body, enhances cardiovascular health, and improves overall endurance. This results in a boost in energy levels, allowing individuals to feel more alert and capable of performing daily tasks more efficiently. Regular moderate exercise also stimulates the release of endorphins, which can enhance mood and promote a general sense of well-being, further contributing to increased energy levels.

In contrast, weight gain, higher cholesterol levels, and fatigue are typically counterproductive effects of exercise or indicative of other health issues rather than benefits derived from moderate exercise. For instance, while exercise often aids in weight management, improper diet or inactivity might lead to weight gain. Similarly, moderate exercise is known to help lower unhealthy cholesterol levels, and should ideally leave individuals feeling invigorated, not fatigued.
