So what does mean "fitness" and what stands for "aerobic" after all? Under the word fitness we should understand the state of wellbeing of a person. Your physical fitness is formed by a set of many different body capabilities like endurance, strength, flexibility, and coordination. Fitness is not only the physical health, but also mental health of a person along with self awareness and emotional satisfaction. So now we see that in general fitness is a state when mind, body and soul are in touch one with each other and what is more - souls do fit the bodies and live in harmony.

The term aerobic along with the exercise was invented by K. Copper from the U.S. Air Force in 1969. All his thoughts were documented in his book called "Aerobics". All the data from the book became the baseline for all aerobic fitness programs that are based on oxygen consumption equivalency.

Talking about the term "aerobic" I can say that it is the most important factor of physical fitness. The origin of this word is Latin and the meaning is following: "aero" means oxygen (air), and "bic" is for bio (life). So any physical activity that requires the intake of oxygen could be called aerobic exercise. All aerobic fitness exercises must maintain increased heart rate and that is why such activity is almost the same as cardio exercises. There are also obvious reasons for this: exercises strengthen lungs and heart, increase cardiac capacity and use body fat and carbohydrates and the fuel (energy source).

Of course there are a lot of types of aerobic fitness exercise. All of them build up your endurance and stamina. Forms of exercise include the following: running, swimming, cycling, long distance skiing, power walking, rowing, use of different exercise machines (bikes, treadmills, and others). Actually all aerobic fitness exercises must be performed at high level of intensity and for a long time period. That is why running is considered as aerobic fitness exercise, but sprinting is not. Regular aerobic fitness exercise gives you a lot of health benefits. They are united in a group called "aerobic training effect" and give your body the following: strengthen muscles that are involved in respiration, strengthen heart muscle (that improves blood pumping efficiency), increase the number of red blood cells in the organism. In addition jogging or rope jumping may stimulate bone growth and reduce the risk of osteoporosis. The digestive system is fed more regularly and is cleaned more effectively.

Because of the very close connection between the mind and the body, mental fitness may now be seen to be in many ways equivalent to physical aerobic fitness. People that are in good aerobic condition tend to be more optimistic, more self-confident; more determined and, generally, have a higher energy level and of course a greater lust for life.

The group of aerobic fitness exercise may be divided into two major sub-groups ? pre-choreographed aerobics and freestyle aerobics (exercise is linked to dance and choreography).
