Exercise is commonly broken up into two subcategories- aerobic and anaerobic exercise. Technically, these terms refer to the presence (aerobic) or absence (anaerobic) of oxygen in cell metabolism, the process by which the cells of the body obtain energy.
In aerobic work, the body uses oxygen to produce energy. Often, this means that the heart and lungs are working harder than usual, in order to get enough oxygen into the muscles. In aerobic activity, the muscles utilize oxygen to convert glucose (often from muscle glycogen stores) into adenosine triphosphate, or ATP, which is essentially a molecular unit of intracellular energy transfer. If the glucose stores in the body become low, the body begins to use fat as fuel.
Aerobic exercise is sustainable for longer periods of time; it is usually performed for twenty minutes or longer. (Examples include running, cycling, cross-country skiing, or walking.) Aerobic works strengthe...

And by tomorrow, he’ll have a million questions. If you’re concerned that you may have herpes and haven’t see...

Red patches on the skin, followed by small blisters, form in most people.
