Regular exercise positively influences body composition by promoting an increase in lean muscle mass and a reduction in body fat. Engaging in consistent physical activity stimulates muscle growth through the process of hypertrophy, leading to a more toned and defined physique. Additionally, exercise boosts metabolism, enabling the body to burn calories more efficiently, even at rest. Over time, this results in improved body composition and reduced fat-to-muscle ratios. Combining resistance training with aerobic activities maximizes these benefits, ensuring a well-rounded approach to achieving and maintaining a healthy body composition.
