People who value health generally pay attention to the amount of fat in the body, because - as everyone knows - too much fat (obesity) can cause many health problems, from the simplest and most inconvenient to the most serious chronic diseases and tumors. However, many people do not know that another component of the body, muscle content, also has an important impact on health.

　　Muscles can strengthen bones and joints. The tension of the muscle protects the key factors of joint stability. Lack of muscle strength will increase the risk of joint deformation, joint degeneration, bulging or prolapse of the lumbar disc. Chronic disease of joints and aging are directly related to insufficient muscle strength.

　　 Compared with fat, muscle has a higher metabolic rate. Maintaining a certain amount of muscle can promote metabolism and reduce the risk of chronic diseases related to metabolic disorders, such as atherosclerosis, dyslipidemia, and diabetes. For the same reason, people with more muscle content have a slower aging rate and will be younger than people of the same age who lack muscle.

　　Muscles are the target organs of most endocrine hormones (hormones), which can increase the effect of hormones. This also includes various sex hormones. Studies have shown that strengthening muscles in the body can improve sexual performance. I think that people often say that "kidney deficiency" is closely related to the lack of muscles in the body.

　　 In short, the amount of muscle in the body has important health significance. When people are concerned about reducing fat, don''t forget to take measures to increase muscle mass in the body.

　　The generation of muscles in the body follows the principle of "use for life, retreat when not in use". In other words, muscles are all exercised. If you do not exercise, eating any food or health products will not increase muscle content out of thin air. The so-called exercise here mainly refers to "struggling". Regardless of sports (such as push-ups, running, swimming, pulling equipment, dumbbells, etc.), or daily activities (such as moving things, going upstairs, climbing, etc.), or even housework (such as cleaning the floor, hand washing, holding children, etc.), as long as When you need to work hard during the activity, it will help increase muscle mass or muscle strength. On the contrary, those activities that do not require force, such as walking, yoga, etc., will not stimulate muscle generation or increase strength.

　　 So, how do you know whether your body’s muscle content or strength is sufficient? The simple way to judge is whether you can do 20-30 push-ups in a row (if not, it means that the upper limb muscles are not qualified); whether it can be continuous Do 20 to 30 sit-ups (if not, it means that the trunk muscles are not qualified); can you go up to 40 steps a little faster (if not, it means that the lower limb muscles are not qualified-except those with heart disease).

　　The more accurate way to determine whether muscle strength is sufficient is to measure it with a grip. Don''t look at the grip is only held by hand, but it can reflect the muscle strength of the whole body.
