A 30-year-old man may still be proud of his strong body and pay no attention to it, but a 40-year-old man must start building muscles; otherwise, the condition of your body will deteriorate at an accelerating rate. Research in the United States shows that if one does not deliberately exercise, starting from the age of 30, human muscles will gradually decrease, and by the time one reaches 75 years old, only 50% of the original muscle mass remains. At this point, chronic diseases become unavoidable.
Muscles are crucial tissues that support the structure of the human body. There are more than 600 muscles throughout the body, accounting for approximately 40% of body weight. Any activity of the human body, even the simplest movements such as blinking or eating something, requires the cooperation of muscles to achieve.
Experts believe that muscles are very important for physical health. They point out that between the ages of 20 and 40, there is not much change in muscles, but after 40, the quantity of muscles starts to decline. Men lose about one-third of their muscle mass, while women lose about half. Simultaneously, muscle strength also begins to wane.
The harm caused by the reduction in muscles is not limited to obesity and decreased strength; it can also become a "co-conspirator" in inducing cardiovascular disease and increase the likelihood of fractures. For men, muscles are like land; if they are not maintained in time, men lose the essence of life, leading to a drop in male hormones, fewer facial hairs, finer voices, vigilant eyes, and reduced sexual ability.
Academician Wang Longde, President of the Chinese Society for Disease Control and Prevention, frankly stated: "Even though I am over sixty, my deltoid muscles and chest muscles are no worse than those of many young people."
This is because Academician Wang has been consistently exercising his muscles for ten years. He practices with dumbbells at home while watching TV or listening to music, and when traveling due to the heaviness of dumbbells, he switches to carrying a lightweight resistance band.
Experts believe that 40-year-old men should not only focus on training their abdominal muscles but also pay attention to leg muscle exercises. If abdominal muscles ensure your health, then leg muscles guarantee your quality of life.
Dumbbells, resistance bands, etc., are simple and convenient strength training equipment. Additionally, jogging, climbing mountains, swimming, cycling, and other activities can also exercise muscles, improving the body's metabolic mode and enhancing cardiovascular capacity. It needs to be pointed out that strength training and aerobic exercise must be combined for optimal results.
