The real concept of "weight gain" is to increase muscle and weight, not just weight gain. Therefore, in addition to the above dietary adjustments, people who are thin should also actively participate in moderate exercise, which is of great benefit to reshaping their bodies.

In order to build a symmetrical figure, thin people may choose jogging, table tennis, swimming, push-ups and other small sports, and then go to the fitness center to exercise some bodybuilding equipment with a large amount of exercise, which is conducive to local muscle exercise and body shape recovery.

In daily life, you can do the following "stomach-strengthening exercises" at your convenience:

On an empty stomach, lie on your back and straighten your legs naturally. After taking a deep breath, bend your knees upward, hold your legs with your hands and keep your thighs as close to your abdomen as possible. After a few seconds, relax your legs and let them return to their original state. Do it five times.
