Aerobic Exercise: Prolonged, moderate - intensity work that
uses up oxygen at or below the level at which your
cardiorespiratory system can replenish oxygen in the working
muscles. Aerobic literally means “with oxygen”, and the
only type of exercise that burns body fat to meet its energy needs.
Bodybuilders engage in aerobic workouts to develop additional heart
/ lung fitness, as well as to burn off excess body fat to achieve
peak contest muscularity. Common aerobic activities include
running, cycling, stair climbing, swimming, dancing, and walking.
Depending on how vigorously you play them, most racket sports can
also be aerobic exercise.
