At around 20 years of age, the body is at its peak of functionality and can be exercised at any level of intensity, and the “regular strength” gained through muscle-strengthening exercises does not disappear even after the exercise is terminated. The heart can improve blood transfusion through endurance exercises. In short, at the age of 20, people can reserve “resources” for their future health. Around the age of 30, a person’s body function has gone beyond its peak, and at this time the body’s joints often make some noise, which is a precursor to joint disease. In order to make the joints to maintain a high degree of flexibility, should do more stretching exercises. Attention should also be paid to the exercise of the cardiovascular system. Exercise should be every Monday, Wednesday and Friday every other day, each time for 5 to 30 minutes of cardiovascular system exercise (jogging or swimming), the intensity is not as big as when you are 20 years old. Compared with 20 years old, people over 40 years old muscle exercisability has decreased by 25%, physical strength gradually decline, muscle atrophy year by year, the body began to blossom. Fatting and the reduction of total muscle mass is related to less muscle, fat consumption is less, and the amount of food is not less than when young, so the stomach will begin to bulge. People over 40 years of age to choose exercise programs should not only be conducive to maintaining a good body shape, but also to prevent common geriatric diseases, such as hypertension, cardiovascular disease and so on. Exercise can be chosen twice a week on Mondays and Fridays, including: 25 to 30 minutes of cardiovascular exercise, moderate intensity exercise, such as jogging, swimming, cycling and so on. People over 50 years old, each exercise can do 10 to 15 minutes of equipment exercises, the weight of the equipment should be lighter than when 30 years old, but the number of times may be more. To prevent accidents, it is best not to use dumbbells. Pay particular attention to the movement of the joints and those muscles that are easy to atrophy.
