1, the purpose principle.

The enthusiasm of physical exercise comes from clear purpose and correct motivation. Therefore, we should first carry out regular ideological education and link the purpose of physical exercise with improving the quality and national image of the whole Chinese nation and promoting the correct development and health of the body. The determination of this goal is helpful to generate positive emotions and consciously overcome various difficulties encountered in the practice process. Secondly, at every stage of physical exercise, we should strive to achieve the expected goals. Physical exercise is a long-term task, and it is not easy to produce obvious changes in the short term. Therefore, there should be clear purpose requirements in each practice stage, and these requirements should become the expected goals of the practitioners. For example, leg flexibility exercises should aim at vertical and horizontal splits, and each exercise combination aims at mastering movements, thus making practitioners interested in the content. Interest itself will promote practitioners to practice actively. Through the combination of class and class, physical strength and brain power, it will inevitably have a good influence on the body, and then change in body shape and temperament. In this way, practitioners will feel rewarded and play an important role in mobilizing and consolidating the enthusiasm of practitioners.

2. Proceed from reality.

The principle of proceeding from reality is to make corresponding practice plans and select corresponding practice contents according to the different ages, genders, physical foundations and practice levels of practitioners. So that practitioners can effectively stimulate all parts of the body in the process of participating in sports, and are not afraid of difficulties or excessive fatigue. For example, when dealing with children, we should choose a combination of exercises with lower difficulty-focusing on basic quality exercises, focusing on all-round exercises, and appropriately selecting content with strong gameplay; For teenagers with a certain foundation, we should choose the movements in the middle and high difficulty group-mainly local exercises, mainly carving various parts of the body, and crossing the grip and leaving the grip. At the same time, we should combine general requirements with differential treatment, put forward general requirements for the similarities of people at the same level, and treat everyone's differences differently. Such as the number of exercises, time, feeling of action, etc.

3. Adhere to the principle of regularity.

When doing calisthenics, we must insist on regularity and perseverance, so that various effective methods in calisthenics can have a lasting impact on all parts of the human body, gradually form a "habit" and make every gesture reflect a "behavioral beauty." Teenagers should have enough time for physical exercise, and qualified schools should set up physical education class at least twice a week to ensure that students have enough time to receive comprehensive and systematic exercise during their school days. This not only helps students to correctly understand the standard requirements of body posture in concept, but also helps students to master the methods and means of physical exercise in practice, and also helps to form biological rhythm, so that the human body can gradually adapt to and prepare for participating in exercise, further improving the effect of exercise, which is of great significance to cultivating students' idea of "lifelong sports".

4. The principle of gradualism.

In the process of teaching physics exercises, we must follow the principle of from easy to difficult, from simple to complex, and gradually improve the teaching difficulty and requirements. Reasonable and orderly arrangement of contents, methods and exercise load should reflect the objective law of physical exercise teaching process. Specifically, warm-up activities should be carried out before class, and then the content to be practiced should be carried out, so that practitioners can enter the practice in the best state, enhance their acceptance, improve the practice effect, and prevent injury accidents; At the end of the course, there should be relaxation activities or games, so that practitioners can eliminate fatigue as soon as possible and produce happy emotions. For those who have just participated in the exercise, they should pay attention to the content of basic exercises, and gradually put forward new requirements with the continuous improvement of physical fitness and sense of action, and gradually transition to higher-level movements.

5. The principle of comprehensiveness.

Aerobics should comprehensively develop all parts of the body, all kinds of physical qualities and basic activities, and carefully "carve" every part of the human body. Teenagers are in the stage of growth and development, and physical exercise should strive to influence the human body in an all-round way, highlight the key points in different stages and give consideration to other aspects. At the same time, it is necessary to combine physical exercise with the cultivation of inner temperament, so that teenagers can have a correct aesthetic consciousness through physical exercise, even if they are well developed and have an elegant and refined temperament, they can grow up healthily in a beautiful artistic environment, making physical exercise an effective means to improve the comprehensive quality of teenagers.

In fact, leg press is not only for beautiful dancing, but also has many benefits in fitness, for example, it can promote blood circulation, reduce muscle fatigue, shape muscle lines and so on. Leg press belongs to static stretching, and he should practice dynamic stretching (kicking) every time after leg press.

The standing posture of ballet is a very simple movement, which requires shoulders to sink, thus highlighting the beautiful lines of the chest and neck; Ask your legs to tighten and your waist to stand upright, so that you can make your posture straight and dignified ... This simple action is not only beautiful, but also directly helpful to health and weight loss. Some students are harmful to their health because of bad habits. For example, many people like to use one-shoulder backpacks for a long time, resulting in uneven development of both shoulders (one high and one low); For another example, many people misunderstand the action of "holding your head up and holding your chest out" as "hunching over your hips". As a result, your waist muscles are weak and your abdomen protrudes day by day, which may lead to premature aging of your waist due to improper exertion. The standing posture of ballet can make you feel a few centimeters taller and make your body lines look softer. The coach will tell you when you practice: imagine yourself as a princess, very lofty and beautiful ... through this "internal and external training", your figure and temperament will be developed.
