It is ok to do sit-ups before going to bed, but you must have perseverance, otherwise the effect is not good. Suggestions are mainly diet control and exercise, eat less foods with high sugar and fat, try to have a light diet, eat more foods with high cellulose and do more exercise. It is important to stick to it, otherwise it will be easy to rebound even if you lose weight.

During sit-ups, abdominal muscles exert more force. Long-term exercise is mainly to improve abdominal strength and make muscle groups more developed, which is one of the effective ways to exercise abdominal muscles. Combined with other aerobic exercises, it can play a role in losing weight and bodybuilding, while simple sit-ups can't consume fat better.

Precautions:

1. Gradually increase the number of sit-ups: For a participant who just started to train abdominal muscles with sit-ups, the number of sit-ups should not exceed 10 repetitions (training the muscle strength of abdominal muscles first). After each sit-up, he should stand up or lie down to rest and let his abdominal muscles relax 10 minutes or more.

2. Do sit-ups slowly: The training goal is mainly the endurance of abdominal muscles, so only by doing sit-ups slowly can we really train the endurance of abdominal muscles.

3. In addition to the movements of the upper body, in order to avoid overloading the lower abdominal muscles to flex the hip joint during sit-ups, the knee joint should also flex during sit-ups. Therefore, for middle-aged men and women whose main training part is the fat in the lower abdomen, proper knee bending and leg lifting can train the muscles of the lower abdomen and achieve the purpose of training the muscles of the abdomen (upper abdomen and lower abdomen).
