In addition to the strength of abdominal muscles, abdominal muscles mainly depend on the thickness of fat outside abdominal muscles. Some people, especially thin people, don't practice because there is less fat outside the abdominal muscles, and it seems that the abdominal muscles are also very good; On the contrary, some people practice for a long time, but their abdominal muscles are not obvious. The main reason is that the fat outside is too thick.

Exercising abdominal muscles should be carried out simultaneously from two aspects.

First, aerobic exercise. Through aerobic exercise, you can lose excess fat all over your body, including your abdomen. Repeated muscle exercises with moderate exercise intensity lasting more than 20 minutes, such as playing ball, skipping rope, cycling, aerobics, running, etc. . . . The so-called moderate intensity means that the heart rate measured immediately after exercise is 140- 160/ min. You can choose a project that you are relatively interested in.

Second, the targeted exercises of abdominal muscles. There are many actions to practice abdominal muscles, but three simplest and most practical actions can practice all abdominal muscles. Sit-ups: mainly practice upper abdominal muscles; Supine leg lifting mainly exercises the lower abdominal muscles; Inclined sit-ups mainly practice the oblique muscles outside the abdomen. These three movements are simple and easy to do, and you can do them in bed.

The above aerobic exercise and targeted abdominal muscle exercise can be carried out every day. Do aerobic exercise for 20-30 minutes first, and then do 20-30 *3 groups of three abdominal muscles.

This will have a good effect if you persist for two months.
