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.
These drugs are not without hazardous side effects, however, and they are legally available only through a physician's prescription.
Anaerobic Exercise - Exercise of much higher intensity than aerobic work, which uses up oxygen more quickly than the body can replenish it in the working muscles.
Anaerobic exercise eventually builds up a significant oxygen debt that forces an athlete to terminate the exercise session rather quickly.
Abduction - Movement of a limb away from the middle of the body, such as bringing the arm to shoulder-height from a hanging-down position. Abyss - A barrier which stands between knowing what needs to be done and actually doing it Accommodating Resistance - Increasing resistance as the lifter's force increases through range of motion.
Nautilus machines are said to provide accommodating resistance.
