1. Ascending height: maintain 45 degrees.

Sit-ups do not pursue the height of getting up. To understand the correct method, the most correct method should be to extend the duration of the 45-degree angle between the body and the ground, so as to effectively exercise the abdominal muscles.

Don't hold your head with your hands.

Generally speaking, sit-ups lose weight by putting your hands and fingers behind your head, but in the process of sit-ups, you often raise your head with your hands, which is easy to cause neck muscle strain. The correct way is to cross your hands on your chest or put your hands on your ears. When you sit up, let your abdomen exert strength, not your arms.

3, with breathing

Reducing the stomach needs to cooperate with breathing, and the muscles of the lower abdomen will become tight to achieve the effect of reducing the stomach.

Extended data:

When doing sit-ups, you should cooperate with reasonable breathing. When doing sit-ups, exhale when leaning forward and inhale when lying on your back. However, if the whole inhalation process is completed mechanically in the supine state, it is not conducive to the completion of the action. Therefore, in order to improve the quality of movement, we must also pay attention to the skills, that is, the process of lying on your back begins to inhale, the shoulder and back instantly touch the pad and hold your breath to abdomen, and the upper body gradually rises. When the upper body is lifted to the abdomen, it will exhale quickly and bow its head forward to complete the action.

Under the age of 30, the best performance of sit-ups should be 60-70 times/minute; At the age of 30, it is best to reach 50-60 times per minute; At the age of 40, it should be about 40 times per minute; At the age of 50, try to reach 30-35 times per minute.
