Ballet originated in Italy and evolved from the performance of aristocratic palaces in the15th century. At that time, the themes were mainly ancient legends, including dances, pantomime, songs and recitations, as well as luxurious costumes and music accompaniment. During the period of Louis XIV in France, ballet developed rapidly and the first Royal Dance Academy was established. Standardized ballet training and determined a set of ballet action system. Ballet is an anaerobic exercise, which takes the basic movements of ballet as the training content, and its bodybuilding strength is incomparable to quantitative fitness exercise. Opening, jumping, straightness and standing are the four elements of ballet, which can contract muscle fibers, make all parts of the body develop in a balanced way and have a beautiful posture, and at the same time, show beauty intuitively and implicitly with melodious music accompaniment. Modern dance is not blindly passionate, but the soothing and relaxing steps are compatible with the elegance of ballet!
