Anaerobic exercise is simply the opposite of aerobic exercise. It's producing energy without oxygen. Anaerobic means without oxygen. An example is a very explosive jump, or a leap or a forty-yard dash or a weight lifting. Due to the way your body works with that form of energy production, it doesn't utilize oxygen but it can produce incredible speed and power; however it fatigues very quickly. So we need both aerobic and anaerobic exercise to balance out our fitness regimen regardless of what type of activity we do; sports or activity, it doesn't matter.
