Note any physical discomfort , especially persistent soreness or stiffness around the joints. This is an overtraining signal. Using a training log and observing basic exercise guidelines, including the need for rest, will enhance your fitness program. By giving your body the recovery time it needs after exercise, you will be able to have real enjoyment in your workouts. An athlete needs to know the energy source required of his or her sport, whether it is aerobic or anaerobic.
All training begins with a good aerobic base, and anaerobic training is added on as needed.
Many sports that are commonly enjoyed require a combination of aerobic and anaerobic capability. Cardiovascular training usually focuses on aerobic training, but training the anaerobic system also has its benefits. Anaerobic exercise does not supply the muscles with oxygen and produces the burning sensation due to lactic acid building up in the muscle being worked. Training the anaerobic system requires high intensity exercise. It is based on the overload principle that the body adapts to harder loads and then becomes more conditioned as a result.
