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.
Anaerobic and aerobic exercise use different energy systems of the body. While anaerobic exercise uses energy from muscles, aerobic exercise uses the energy stored in your body from carbs, proteins, and fats in combination with the oxygen we breathe to make energy readily available to the muscles.
