Sit-ups, if there is abdominal pain, should be temporarily stopped, and then continue after a little relief. In the sit-ups, if too much exercise at once will lead to lactic acid accumulation, thus causing abdominal muscle soreness, if the intensity of the exercise is relatively large, muscle strain or abdominal cramps, will also lead to abdominal soreness. Regardless of which of the above causes of abdominal soreness, the exercise should be temporarily stopped for rest or appropriate abdominal massage or hot compress to improve the symptoms of soreness. If the patient’s symptoms are relieved after rest, the exercise can be continued. If the symptoms are still not relieved after rest, the patient should go to a regular hospital for relevant examination in time to make a clear diagnosis and then treat the symptoms. From the above, it can be seen that if abdominal pain occurs when performing sit-ups, it is not advisable to continue with the exercise.
