Body composition, defined by the ratio of fat to muscle mass in the body, plays a significant role in determining overall fitness. A lower body fat percentage typically correlates with enhanced athletic performance and metabolic function. Individuals with a healthy body composition often show improved strength, endurance, and flexibility, leading to better functionality in daily activities. Additionally, it can impact self-esteem and mental well-being. Monitoring body composition helps individuals set realistic fitness goals and adapt their training and nutrition plans for optimal health outcomes.
