For those thin people who sit in the office for a long time, it is necessary to take some time to exercise every day, which is not only beneficial to improve their appetite, but also to make their muscles strong and fit. The muscles of the human body are "put into use and discarded". If you don't exercise for a long time, muscle fibers will contract and weaken, and people will look thin.

In terms of exercise mode, jogging is a good choice, because the number of gastrointestinal peristalsis increases obviously when people jog, which can consume human energy and make people have a big appetite when eating. Generally speaking, a large amount of exercise, short-term exercise and rapid explosive exercise can all have the effect of gaining weight, which is also the most taboo for people who want to lose weight.

The exercise of people who want to gain weight is mainly "weight training", rather than "aerobic exercise" emphasized by people who lose weight. Because "aerobic exercise" promotes energy consumption, and "weight training" is used to increase the proportion of muscles. With the help of dumbbells, barbells and training equipment, combined with the complete contraction and relaxation of large muscle groups, muscle construction can be realized.

So what is the big muscle group? It is what we call chest muscles, abdominal muscles, back muscles, leg muscles, biceps and triceps (arms). Through weight-bearing training and dietary supplement, large muscle groups can grow, and relatively, they will also accumulate some weight.

At present, in the United States, we have begun to try to carry out proper weight-bearing training for the elderly, and supplement foods to increase the proportion of muscles, so as to improve symptoms such as malnutrition, fatigue, depression, muscle failure, poor immunity and easy illness. For the elderly with chronic diseases, it will also reduce the chances of complications and poor prognosis.
