Aerobic exercise is a physical activity that is somewhat aligned with anaerobic exercise. Aerobic exercises, in particular, use oxygen to allow the muscles to generate energy and include all types of physical activity, but are most often limited to those that are done at levels of intensity that may be identified as being moderate and continuously performed for sustained periods of time.

Aerobic exercise works to maintain a targeted heart rate while using oxygen to burn fat and glucose in the production of adenosine triphosphate, or ATP, which is the transporter of basic energy for every cell in the body. At the outset of aerobic exercise, glycogen becomes broken down in order to furnish glucose but, if there is no glucose present, this culminates in the decomposition of fat. This subsequent decomposition of fat is a process which takes time and thus causes performance levels to taper off while awaiting additional energy input. When the body begins using fat as a fuel, it enters the state that marathon runners have termed, "hitting the wall."

There are a number of conventional forms of aerobic exercises and the standard ones are performed at energy levels that may be termed high and maintained for longer time periods. In the case of an athlete running a number of miles at a moderate pace, this is regarded as being similar to an aerobic exercise, while sprinting is not considered to be aerobic training. In fact, any physical activity that entails rhythmic motion can be termed as aerobic exercise, though activities that are discontinuous are not thought of being as aerobic exercises.

A major criticism of aerobics is that it is not sufficient for professional requirements, such as those established for athletes, military, and emergency personnel. This may be because aerobic exercises do not offer muscular strength, especially in the upper body.
