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. Anaerobic exercise (the kind of exercise to which bodybuilding training belongs) burns up glycogen (muscle sugar) to supply its energy needs. Fast sprinting is a typical anaerobic form of exercise.

Ectomorph - The ectomorph is the extreme somatotype. An ectomorph is characterized smalls bones and very little muscle mass. An ectomorph will have a very steep angle in his or her thorax, and the ribs are closer together. Ectomorphs are generally better endurance athletes than bodybuilders by nature, and may excel in cross country running. That is not to say an ectomorph cannot bodybuild. It is very possible to achieve great gains in mass and strength regardless of being an ectomorph.
