In the simplest terms the difference comes down to the oxygen. With aerobic exercise oxygen is carried through your breath to the muscles giving them the energy needed to sustain the effort. Oxygen is not present with anaerobic exercise. Exercise requires energy. When we exercise aerobically our bodies use glycogen and fat as fuel.
In contrast to aerobic respiration, anaerobic respiration describes a set of chemical reactions that allow cells to gain energy from complex molecules without oxygen. Your muscles cells perform anaerobic respiration whenever you exhaust the oxygen being delivered to them, such as during intense or prolonged exercise.
