(1) Fitness exercise is the mother body of bodybuilding exercise
From the perspective of historical evolution, fitness exercise gave birth to bodybuilding. Although there are disputes about the origin of physical fitness exercises: "labor theory", "game theory" and "activity theory", there is no doubt that it is the mother of bodybuilding. And the origin is by no means unitary, but diverse. It is not only related to production, labor and life (such as hunting, fishing, gathering, planting, farming, etc.), but also related to military, religion, medicine, entertainment and education (such as fighting, running, jumping, throwing, climbing, games, etc.). Acrobatics, dance, entertainment, sacrifice, etiquette, art, etc. are closely connected. Scholars also believe that the three most direct sources of human physical fitness should be the initial education, culture and entertainment, and medical care. In short, they are all of the above. The development of activities and its comprehensive factors have promoted the development of physical fitness and gave birth to ancient bodybuilding. For example, the naked exercise of ancient Greece, the movement of ancient Rome and the lifting of heavy objects, and the development of modern bodybuilding. It has greatly enriched the connotation of modern fitness sports and promoted the development of fitness sports.
