This expression, by itself, directly means "with oxygen", but it comes alive when used as an adjective to identify exercise. Aerobic exercise is exercise that is energetic enough and vigorous, lasts long enough and is done regularly enough to keep your heart and lungs in good conditions. Aerobic exercises burn fat faster than any other type of exercise. Aerobics is a type of physical exercise that integrates rhythmic aerobic exercise with stretching and strength training routines with the objective of improving all elements of fitness (flexibility, muscular strength, and cardio-vascular fitness). It is generally performed in group with background music and this is directed by an instructor, although it can be practiced solo and without musical accompaniment.
Regimens associated with this purpose admit any form of vigorous exercise, such as cycling, jogging, and swimming. More narrowly, the terminology behind "aerobics" points to the efficacy of oxygen as it is used by the body during the prolonged exercises that are indicated.
Naturally, aerobics is not a recent idea, and it had not its origin in the 1980s. Instead, it was Dr. Kenneth H. Cooper (air force physician and former track runner) who in 1968 would change the world of exercise as it was known by publishing a book entitled "Aerobics," thus coining a term thus far not used. An eloquent speaker, splendid motivator, and engaging television personality introduced him into the living rooms of thousands. In many ways this publication started a craze which got people exercising in droves.
The exercise regimens were simple to start and easy to follow. Aerobics had to be exercises that would pressure the body to elevate its oxygen intake; consequently, the exercises had to be continuous and at the same time rhythmic to avoid declines and spines in the oxygen consumption. All the large muscle groups were used, increasing the work heart and lungs were performing.
