Instead of concentrating on specific objectives like athletic competition, building bigger muscles, or concerns about looks, general fitness training aims to improve overall health and well-being. Regular, moderate exercise and a healthy diet can prevent age- or lifestyle-related health declines and the string of heart and organ failures that come along with inactivity and a poor diet, as well as improve general health-related appearance indicators like muscle tone, healthy skin, hair, and nails. By accelerating metabolism, diets themselves help people burn more calories, a process that is further accelerated when they put on more lean muscle. A routine of aerobic exercise can boost metabolism and burn fat.
