1, a ball in your chin. When you can't control the stress on your neck, you can put a ball between your chin and your neck, which can avoid the flexion and extension of your neck, thus avoiding the stress on your neck.

2. Put your hands on your ears. Some people will hold their heads in their hands when doing belly rolls, which will cause the neck to exert force when doing belly rolls. When doing belly roll, it is recommended to put your hands next to your ears or worse, put them on your chest, and give less auxiliary stimulation to your head.

3, abdominal breathing, breathing style is also very important. In the process of doing abdominal rolling, practicing abdominal breathing can not only better activate abdominal muscles, but also avoid using the auxiliary breathing muscles of the neck, thus reducing the stress on the neck.

Precautions for doing sit-ups:

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

2. The training goal is mainly the endurance of abdominal muscles. Therefore, 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 the sit-ups are all carried out in the sagittal plane (shoulder parallel sit-ups), 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.
