Which of the following is a benefit of regular physical exercise?

Regular physical exercise significantly contributes to improved overall physical and mental health. Engaging in consistent physical activity has been shown to enhance cardiovascular fitness, increase strength and flexibility, and support a healthy weight. Furthermore, exercise releases endorphins and other neurotransmitters that elevate mood, reduce anxiety, and alleviate symptoms of depression.

The benefits of exercise extend beyond physical changes; they also bolster cognitive functions and improve sleep quality, leading to a more balanced and robust mental state. Hence, when considering the wide-ranging positive effects of regular exercise on both the body and mind, it becomes evident why this choice is identified as the correct answer.
