Are sit-ups aerobic exercise? What are the benefits of sit-ups?

Have you ever done sit-ups in your life? Today, let's learn about it together. Is sit-ups an aerobic exercise? What are the functions of sit-ups? If you want to know, let's learn about it together.

Sit-ups are an anaerobic exercise.

1. The biggest feature of anaerobic exercise is that the oxygen intake during exercise is very low. Due to the high speed and strong explosive force, the sugar in the human body does not have time to be decomposed by oxygen, and has to rely on "anaerobic energy supply". This kind of exercise will produce too much lactic acid in the body, causing muscle fatigue and inability to last long, muscle soreness and shortness of breath after exercise.

2. Sit-ups are the most basic exercise, just like push-ups, and almost everyone has done them. There are still many fitness enthusiasts who regard it as the best choice for training abdominal muscles.

3. Since sit-ups are very explosive and fast, the blood oxygen supply is insufficient, which will cause low oxygen intake. Long-term exercise will produce a lot of lactic acid, causing muscle soreness. Therefore, you must pay attention to the method of doing sit-ups. It is more appropriate to do them in groups, and there must be a certain interval between each group.

1. Sit-ups can exercise the abdominal muscles, tighten the abdominal muscles, and better protect the internal organs in the abdominal cavity.

2. Sit-ups can also stretch the back muscles, ligaments and spine, and can regulate the central nervous system by stretching the spine. Moderate exercise can also improve the body's immune function, thereby enhancing the body's disease resistance.

3. You can also exercise your groin. There are many capillaries and acupuncture points in the groin. Doing sit-ups can stimulate the blood vessels in the groin through exercise, promote blood circulation in the abdomen, and thus treat and relieve gynecological diseases.

When should you do sit-ups?

One of the best times to do sit-ups is at night, which is basically 2 hours after dinner or 2-3 hours before bedtime, around 8-9 p.m. Because most of the food in the body has been digested 2-3 hours after dinner or before bedtime, the body will not feel particularly tired. Proper exercise can also help consume excess calories for the day, and exercise at this time will not affect sleep at night (of course, this is recommended on the basis of not exercising too much). Moreover, compared to other best times such as 3-4 p.m., sit-ups at night are easier to do. People study or work all day, and basically the time they can spare for exercise is at night.

How many sit-ups should you do at a time?

Before going to bed every night, fully exercise your waist, and then go to bed. Do it in 4-5 groups, 15-20 in each group, and the interval between each group should not exceed 90 seconds. If you feel it is difficult, you can reduce it to about 15 in each group. The number of groups must not be less than 4 groups. You will see results if you persist for half a month, and it will be better if you persist for a long time.
