Aerobic vs. Anaerobic. To understand the relationship between weights and calories, you need to know the difference between aerobic and anaerobic exercise. Sustained aerobic exercise, like steady jogging or cycling, is low intensity and can thus be done for a longer period of time.
absolute advantage. In the theory of international trade, a country or firm has an absolute advantage if it can produce a product (good or service) more 'efficiently' (cheaply) than others. First suggested by the UK economist Adam Smith (1723-90) as an extension of his division of labor doctrine. See also absolute cost advantage and competitive advantage.
Absolute Advantage. Absolute Advantage exists when a country can produce a good at a lower expense than another country. Say there is Country A whose climate and amount of arable land makes for the profitable cultivation of rice, while Country B's mineral resources make it well suited for production of iron ore. So Country A has an absolute advantage in the production of rice and Country B has an similar advantage in the extracting and refinement of iron ore. As long as there is sufficient demand for both goods in each country (a reasonable assumption considering both are staples in today's era), then there is an opportunity for mutually beneficial trade between the two.
