Considering the total body, there are six elements of fitness: aerobic capacity, body structure, body composition, balance, muscular flexibility and strength. Let's consider each one of these. Aerobic capacity is your cardiovascular system's ability to transport oxygen to working muscles to serve as fuel for energy.
