Which of the following is a benefit of regular exercise?

Regular exercise offers numerous benefits for overall health, and one of the most significant advantages is the decrease in body fat. Engaging in a consistent exercise regimen promotes the burning of calories, which can lead to a caloric deficit—a fundamental requirement for fat loss. Additionally, exercise increases metabolic rate, helping the body to utilize stored fat as energy more efficiently. When combined with a balanced diet, regular physical activity can help individuals achieve and maintain a healthy body composition.

While increases in muscle mass can also occur as a result of weight training, this is typically not the primary or most immediate benefit observed with regular exercise for all individuals. Improved vision and enhanced hair growth are not direct outcomes of regular exercise and respect other health aspects that may not correlate directly with physical activity levels. Thus, a decrease in body fat is one of the most universally accepted and measurable outcomes of regular physical activity.
