Academician Wang Longde said that he has been exercising every day for many years, practicing dumbbells while watching TV and listening to music at home, and taking a portable stretcher with him on business trips. A stretcher can be stretched with both hands and feet. By changing the stretching direction, you can exercise the deltoid and pectoral muscles of your arm, and the effect is no less than dumbbells. He practices about 1 hour every day. The main function of dumbbells and tensioners is to exercise muscles. Wang Longde bluntly said: "Although I am over 60, my deltoid and pectoral muscles are no less than many young people." Wang Longde said: Many people say that I am taking calcium tablets. How can I still have osteoporosis? In fact, impact exercise can prevent osteoporosis, and blood calcium can be transferred to bones through exercise impact, otherwise eating more calcium will have no effect. The impact sport recommended by Wang Longde is simulated skipping rope. "I always jump two hours after dinner, do it while watching TV, and then I'm done. It's not boring at all. " Wang Longde also said that he eats fruits before meals, and it is best to eat and absorb them on an empty stomach before meals. The American Cancer Society has done research. People who eat less fruit have the highest risk of lung cancer, while people who eat fruit regularly have a much lower risk of chronic diseases. Milk calcium is best absorbed. He drinks 200ml milk every morning and a small box of 100ml yogurt after lunch and dinner. He gargles after every meal, because food scraps can cause periodontitis, which is an important factor leading to cardiovascular and cerebrovascular diseases.
