A 30-year-old man may still take pride in his strong body and pay no attention to it, but a 40-year-old man must start building muscles; otherwise, your physical condition will deteriorate at an accelerating rate. Studies in the U.S. have shown that if one does not exercise deliberately, starting from the age of 30, human muscles gradually decrease, and by the time one reaches 75 years old, they will only have 50% left. At this point, chronic diseases are inevitable.
Muscles are important tissues that support the structure of the human body. There are over 600 muscles in the human body, accounting for approximately 40% of body weight. Any activity of the human body, even the simplest movement such as blinking or eating something, requires the cooperation of muscles to be accomplished.
Experts believe that muscles are crucial for physical health. They point out that between the ages of 20 and 40, there is little change in muscle mass, but after the age of 40, muscle quantity begins to decline. Men lose about one-third of their muscles, while women lose about half. Muscle strength also starts to diminish.
The harm caused by muscle loss is not just obesity and reduced strength; it can also become a "helper" in inducing cardiovascular disease and make one more prone to fractures. For men, muscles are like land; if they are not maintained in time, men lose the foundation of life, leading to a decrease in male hormones, less facial hair, finer voice, weaker eyesight, and decreased sexual ability.
Academician Wang Longde, President of the Chinese Society of Preventive Medicine, frankly said: "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 lightweight resistance bands.
Experts believe that 40-year-old men should not only focus on abdominal muscle training but also leg muscle training. If abdominal muscles ensure your health, then leg muscles guarantee your quality of life.
Dumbbells, resistance bands, etc., are all 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 is worth noting that strength training and aerobic exercise must be combined.
