Anaerobic exercise

Anaerobic exercise unlike aerobic exercise does not involve use of oxygen to generate energy. This type of exercises are used to develop muscles so that the person can do great in short duration and high intensity activities.


Aerobic exercises are generally running, walking, bicycling and swimming. These are done for longer durations of time with less effort compared with an anaerobic exercise. Oxygen is used up to produce energy in aerobic exercises. This has many long term health benefits.


Unlike aerobic exercise anaerobic exercises are not performed for long term benefits but for short intense bursts of energy needed by muscles for performing wonderful feats. Many athletes and bodybuilders resort to this type of exercises.

Strength training

Strength training is for doing physical exercises and has many health benefits. It involves use of heavy weights to oppose gravity or using elastic forces. This has several health benefits apart from increasing the size and strength of muscles.


Strength training is done initially by lifting as much weight as possible by a person. Then the muscles respond to grow larger and stronger. As the person repeats the process the muscles grow larger and he/she need to steadily increase the weights also. This is how the process expands muscles gain size and strength.


Strength training reduces the potential for injuries to the body. It improves cardiac functioning and thus reduces the chances of a heart attack. Bone, muscles and ligament get strength and grow over time. Cholesterol level also increases.
