Sit-ups do not mean that the higher the height, the better. They need abdominal strength combined with even breathing, so that the meat on their stomachs will become tight. In fact, there are many ways. You can put your hand on your ear or chest. The correct way is to extend the duration of 45-degree angle between the body and the ground as much as possible, at least 30 seconds at a time, and you will be very satisfied with the effect.

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 (training 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, sit-ups: the muscles of the upper abdomen of the human body, mainly rectus abdominis, oblique muscles outside the abdomen and oblique muscles inside the abdomen. Therefore, if sit-ups are carried out on the sagittal plane of the upper body, the training effect of the external oblique muscle and the internal oblique muscle will be obviously limited. Only by increasing the rotation of the longitudinal axis of the body (from the right shoulder to the left leg and from the left shoulder to the right leg) can abdominal muscle training's uncoordinated state be avoided.
