Fitness and bodybuilding, the former depends on the overall sense of coordination and proportion, while the latter challenges the limit of human muscle mass. Fitness also depends on proportion, but the strength of a single place will become your characteristic (such as Tom prats, the king of legs, and Liplister, the king of martial arts). If some places have a great influence on the overall coordination, fitness is not good. So fitness as long as it is exercise is fitness, playing table tennis, badminton, swimming and running.
