Body Builder Question:

Prolonged, moderate-intensity work that uses up oxygen at or below the level at which your cardiorespiratory (heart-lung) system can replenish oxy-gen in the working muscles. Aerobic literally means with oxygen, and it is the only type of exercise which burns body fat to meet its energy needs. Bodybuilders engage in aerobic workouts to develop additional cardiorespiratory fitness, as well as to burn off excess body fat to achieve peak contest muscularity. Common aerobic activities in-clude running, cycling, swimming, dancing, and walk-ing. Depending on how vigorously you play them, most racquet sports can also be aerobic exercise.
