People who exceed 20% of the standard weight are obese, and those who are below 20% are thin. Emaciation can also be divided into simple type and secondary type. Simple emaciation is mainly due to poor appetite, poor digestion and absorption ability, irregular life, lack of physical exercise that makes the body unable to fully develop, or excessive fatigue and genetic factors that make the energy consumed greater than the energy intake. Secondary consumption is mainly caused by some chronic wasting diseases or endocrine gland dysfunction, and patients with secondary consumption should be treated under the guidance of doctors.

Simple and thin people have poor digestion and absorption ability and consume a lot of energy in activities, so if they want to become strong and fit, they must do everything possible to make the body's energy storage greater than consumption. Some people simply take a lot of tonics or tonics, hoping to achieve the purpose of strengthening the body and changing the body, and the effect is not obvious. To increase the body's energy storage, it is necessary to enhance appetite and digestion and absorption; The best way to enhance appetite and digestion and absorption ability is to participate in sports.

Fitness with equipment can make people's metabolism vigorous, play a good massage role in the digestive system, promote the secretion of digestive juice and gastrointestinal peristalsis, and make more nutrients absorbed and transported to all parts of the body. Through the contraction and relaxation of muscles, blood circulation is strengthened, blood flow through muscles will increase, oxygen and nutrition obtained by muscles will also increase, and muscle fibers will gradually become thicker during exercise.

Equipment bodybuilding can also improve the regulation function of nervous system, improve the nutritional status of tissues and cells, and promote the growth and development of tissues in various parts of the body. After long-term exercise, the function of internal organs can be enhanced, muscles developed and weight gained. People with flabby and wrinkled skin, muscular atrophy and thin figure will gradually become strong and plump.

Full figure should not be the accumulation of fat, but should be well-proportioned and strong muscle tissue. Therefore, it is very important for thin people to choose suitable bodybuilding exercises. Instrumental exercise has the best effect on developing muscles. Therefore, thin people should practice dumbbells, barbells, tensioners and combined fitness equipment. However, every time you exercise, you must master the appropriate amount of exercise. If the amount of exercise is too small, you can't strongly stimulate muscle tissue and achieve the purpose of exercise. Too much exercise, energy consumption will be greater than compensation, of course, it is impossible to plump up. Excessive fatigue can also damage your health. Under normal circumstances, start to choose a small amount of exercise, and gradually increase the amount of exercise in the future.

The standard to measure whether the amount of exercise is appropriate should be that the pulse after exercise should not exceed 170 times per minute. Because when the number of heartbeats increases, the output blood per heartbeat increases, but if the number of heartbeats exceeds 170 times per minute, the output per heartbeat will decrease. It is impossible for the body to get more oxygen and nutrition. A coach should not exercise for less than 30 minutes at a time. Generally, it is advisable to exercise once every other day to eliminate the fatigue of the body after exercise and fully supplement the consumed energy.

In the process of exercise, we should also pay attention to scientific diet, so that the body can get enough nutrition and promote its growth and development. It is also important to develop a good lifestyle, be emotionally stable and get enough sleep, which is very important for absorbing nutrition, reducing energy consumption and improving exercise effect.

Losing weight is not formed in a short time, and it is impossible to become strong and plump after several exercises. This requires a process. Under normal circumstances, when you start exercising, you will not gain weight immediately, and sometimes you may lose weight. This is because the body's fat and water are consumed during exercise. If you continue to exercise, the functions of various organs of the body will gradually improve, biochemical changes will occur inside the muscles, the muscles will become strong and stout, and the weight will increase.

As long as you have perseverance, perseverance, persist in exercise, pay attention to gradual progress, combine work and rest, and eat scientifically, your body will certainly become plump and fit.
