Anaerobic exercise, if not the exact opposite of aerobic exercise, is considered its equivalent.
The main difference between aerobic and anaerobic exercises is that the former uses oxygen to produce energy in the muscles. The second makes use of carbohydrates.
When doing activities for long periods of time that use oxygen to generate muscle energy, these are called aerobic exercises. Anaerobics are exercises of greater intensity and done continuously, of short duration.
