The benefits of bodybuilding (1) can first effectively develop the whole body muscles and increase strength.
Muscles, bones, joints and ligaments in the human body. * * * together form a motor organ, which enables the body to perform various complex and delicate movements. And the motive force of all these movements is those large and small muscles. In bodybuilding training, trainers should often use various barbells, dumbbells and other instruments to carry out weight-bearing exercises, and exercise muscles in all parts of the body, especially in each exercise, so that muscles are strongly stimulated, so that muscle fibers become thicker, the capillary network in muscles increases, and the physiological cross-section of muscles increases, making muscles plump, strong and developed, that is to say, muscle blocks increase.
In addition, due to the improvement of the regulatory function of the central nervous system, especially the increase of the intensity and concentration of neuromodulation, the function of our nervous system has become stronger. Under the influence of strength training, the content of contractile substances such as actin and myosin in muscle cells increases, and the fat decreases, which makes the elasticity and viscosity of muscles increase. As a result of all these changes, muscle strength has greatly increased, especially the strength of some local muscle groups can reach a fairly high level. For example, some athletes with heavy achievements can bend and bend the back of the neck with a weight of 90kg, which shows that their arm strength is amazing. The muscle strength of the trunk and legs is even more amazing. For example, the Russian heavyweight bodybuilder is not only muscular, strong and powerful, but also a super strongman. Three big moves? The sum of the results (bench press, hard pull and squat) reached 960kg, with an average of 320kg for each item. He is a real Hercules.
(2) improve body posture and correct deformity.
Body shape mainly refers to whether the proportion of all parts of the body is symmetrical, coordinated, balanced and harmonious, and whether the main muscle groups have beautiful lines. Body posture mainly refers to whether the posture of the whole body and main parts is correct and beautiful. Our country has attached great importance to posture since ancient times, emphasizing that a person should stand, sit and walk. Indeed, if you don't pay attention to the correct posture for a long time, it will affect the normal growth and development of some bones. If some teenagers are ashamed to grow too fast in height, they will consciously hold the back of the thoracic arch, and the spine (thoracic vertebra) will be abnormal after a long time? s？ Form, and form a hunchback. Another example is that many teenagers carry heavy schoolbags on one shoulder. Over time, one shoulder is high and one shoulder is low, which leads to scoliosis. In the south, some teenagers take part in heavy physical labor too early, such as carrying heavy loads for a long time, which will advance the ossification of femur and seriously affect the growth of height. We say that early weightlifting training in the right way will not affect the normal development of height, but will long-term work pressure? Press it? Affect physical beauty.
Various movements of bodybuilding can have a good influence on the growth and development of some parts of the body, and promote muscle development and bone growth. Scientific training can also reduce the fat content in muscles and achieve the purpose of reducing fat and losing weight. These changes can effectively improve people's figure and posture. If the deltoid muscle is developed, the shoulders will be wide; Enlargement of latissimus dorsi can make the body appear beautiful inverted triangle; When the abdominal muscles are developed, the abdomen will be flat and firm. Make men burly and heroic; Women become fit, elegant, flexible and beautiful.
It is precisely because all kinds of movements in calisthenics can have a great influence on all parts of the body, so when a person's body and posture have some defects, he can choose some suitable movements to exercise to correct the deformity. If the proportion of limbs is out of balance, you can practice the side with poor muscle strength first to make it developed so as to achieve symmetrical coordination. Because of this function of bodybuilding, some movements have been further used in medical sports to restore some functions of limbs and make the body fit.
(3) improving health and physical fitness.
Regular bodybuilding exercises can have a good influence on the functions of internal organs such as cardiovascular system, respiratory system and digestive system.
Aerobics can strengthen the myocardium, increase the volume of the heart and enhance the elasticity of blood vessels, thus improving the contractility of the heart and the diastolic ability of blood vessels, making the heart beat vigorously, increasing the cardiac output, reducing the number of heartbeats to about 60 beats/minute, thus increasing the rest time of the heart, thus saving the phenomenon. Because the working ability and reserve ability of the heart have improved, it can bear a greater burden. Bodybuilding can also increase red blood cells, white blood cells and hemoglobin in the blood, thus improving the nutritional level, metabolic ability and resistance to diseases of the human body.
Bodybuilding also has a good influence on the function of respiratory system. It can improve the depth of breathing and increase the amount of gas exchange per breath. This is not only beneficial to the rest of respiratory muscles, but also can improve the functional reserve of respiratory system to meet the needs of gas exchange during strenuous exercise and improve the functional level.
Bodybuilding can also improve the function of digestive system. Because muscle activity consumes a lot of nutrients (especially energy substances), it needs to be replenished in time. At the same time, muscle activity can promote gastrointestinal peristalsis, increase digestive juice secretion, improve digestion and absorption, and increase appetite.
Fitness exercise can improve the level of human hormones, especially male hormones, thus improving sexual function. Insisting on scientific fitness training for middle-aged and elderly people can enhance renal function, enhance male vitality and increase certain masculinity.
(4) Improve the function of nervous system and cultivate tenacious will.
The central nervous system consists of the brain and spinal cord, and its highest command organ is the cerebral cortex. On the one hand, it manages and regulates the activities of various organs and systems of the human body and maintains the balance of the internal environment of the human body; On the other hand, it maintains the balance between human body and external environment.
Bodybuilding is carried out under the control of the central nervous system. Conversely, bodybuilding can also improve the functional level of the central nervous system. It can improve the intensity and concentration of neural processes, improve balance and flexibility, and thus improve the adaptability of the body to the internal and external environment. People who often insist on bodybuilding exercise can generally sleep soundly and deeply, and rarely suffer from neurasthenia.
Hard aspects of bodybuilding training 1. Lots of training.
Fitness classes range from 1 hour to 3 hours. There are several exercises to be done in a class, and each group is required to practice until they can't get up. It takes hundreds to thousands of times to do aerobic exercise, such as abdominal muscle exercise, various jumping exercises, fat removal and weight loss.
2. High training intensity
High-intensity muscle strength training is extremely stimulating to nerves and muscles, and the requirements for the heart are also very high, because this extreme intensity anaerobic training is very stimulating to the heart, and sometimes the pulse reaches 10 second for more than 30 times.
3. Muscle pain
The body often comes into contact with instruments, which causes the trainer's wrist, palm, clavicle, sternum, lumbar spine, knee joint and other links to bear continuous pressure. So there is a feeling of backache and muscle swelling.
In short, bodybuilding training can cultivate athletes' tenacious perseverance, and cultivate perseverance qualities that are not afraid of weight, suffering, pain, fatigue and annoyance.

Natural bodybuilding
In the natural bodybuilding competition, bodybuilders routinely check illegal drugs, and once they find violations, their right to participate in the future will be revoked. Drug testing can be done through urine samples, but in many cases, it is replaced by a lower-cost lie detector. Illegal drugs refer to substances that normal people should not accept. Different natural bodybuilding organizations have different definitions, which do not necessarily include only those drugs prohibited by law. Steroids, prohormones and diuretics are generally prohibited by various natural bodybuilding organizations. Natural bodybuilding organizations include NanBF (North American Natural Bodybuilding Federation) and NPA (Natural Fitness Association). Natural bodybuilders claim that their methods pay more attention to competition and a good lifestyle than other forms of bodybuilding.

women's bodybuilding
In the 1970s, women began to take part in bodybuilding competitions, which were popular for some time. In order to get a better figure and prevent osteoporosis, women began to strengthen strength exercise as never before. But many women are still afraid that strength training will make their bodies swell, or think that strength is only for men. But strength training actually has many benefits for women, such as increasing bone density to prevent osteoporosis and improving muscle strength and body balance. In recent years, fitness and sports competitions have begun to rise. These competitions don't have strict requirements on muscle development level like bodybuilding competitions, which provide another choice for women. 1980 the first session? Miss Olympia?
