Aerobics is an activity or physical exercise that the body needs to be physically fit and can be maintained for a long period of time, it combines rhythmic exercise and strength training. Its goal is to improve all the elements of fitness (flexibility, muscular, strength and cardio-vascular fitness). It trains the heart, lungs and cardiovascular system to deliver oxygen more quickly to every part of the body to keep it in good condition. Aerobic exercise burns fat faster than any other form of exercises. It is generally practiced by group with background music which is usually led by an instructor although it can be done by solo and without musical accompaniment. A person who is physically fit can work longer and more vigorously.

The regimens were easy to start and follow, the exercise had to be continuous to avoid declines and spines in the oxygen consumption. The terminology behind aerobics simply refers to any form of exercise that will get your heart pumping for a continuous period of time, which in turn will increase your oxygen intake. This will lead to fat burning and subsequent weight loss.

The word aerobic directly means "with oxygen" or "in the presence of oxygen", it defines as a mode of conditioning the body in order to increase its circulation as well as its breathing competence.
