What are the benefits and disadvantages of doing sit ups before going to bed?

The good thing is exercise, and the bad thing is that it's not good to sleep.

There is no good or bad.

The benefits of doing sit-ups at night are:

1. Enhance the strength of abdominal muscles to slow down and tolerate meat;

2. Enhance the elasticity of abdominal muscles;

3. It has a protective effect on the back;

4. Improve posture;

5. It is conducive to sleep and increases sleep quality;

6. Enhance intestinal and gastric function;

7. It is conducive to **, reducing the possibility of low fat accumulation on the lower abdomen.

1. Sit-ups can improve muscle flexibility and muscle strength.

There are many studies that believe that sit-ups can improve flexibility and muscle strength. Flexion of the spine has been shown to aid in the delivery of nutrients to the intervertebral discs, which can help prevent bone stiffness. In addition, sit-ups can also improve stability in the core area of the body.

2. Sit-ups are not so good for belly loss.

In a 2011 small, controlled experiment in Illinois, one group did a certain number of sit-ups every day, while the other did nothing. After six weeks of detailed measurements, the researchers found that sit-ups had no effect on waist circumference and the area of abdominal fat.

Therefore, if you want to lose belly, it is not enough to rely on sit-ups, you have to eat a balanced diet, plus aerobic exercise to lose fat all over the body.

3. Sit-ups may hurt your lower back.

A health check-up in the United States showed that 56 percent of soldiers suffered back damage as a result of long-term sit-ups. The Canadian military has removed sit-ups from the Soldier's Training Catalogue and replaced it with a 44-pound (about 40-pound) sandbag for exercise.

Stuart McGill, a professor of biomechanics spine at the University of Waterloo in Canada, has done several experiments with pigs (whose spine is more similar to that of humans than other animals), by mimicking the posture of a person doing sit-ups, constantly bending the pig's spine for several hours at a time. He then examined the pig's vertebral disc and found that the bulge had been squeezed into a pointed shape when it was bent. If the same thing happens to a person, this will compress the nerves, causing back pain and possibly even a herniated disc.

Of course, these findings only illustrate the consequences in extreme cases, as well as the likelihood of injury. People are still different from pigs, and it's almost impossible for people to do sit-ups all the time for hours. Therefore, in life, no one will cause a herniated lumbar disc because of dozens of sit-ups every time.

4. Some people are not naturally suitable for sit-ups.

In the same exercise, some people get injured after doing a little bit, and some people persist for more than ten years and are still fine, we call this situation physical differences, and the main reason for physical differences is the difference in genetics. Therefore, some people are not suitable for doing sit-ups, and they have back pain when they do it; And some people do dozens of sit-ups a day and stick to it for more than ten years. If you're not sure what kind of body type you have, it's best to take it easy when you first start exercising, gradually increase the amount, and learn to listen to your body's feedback.
