First, cooperate with breathing. Second, don't hold your head in your hands. Third, the height of getting up: keep an angle of 45 degrees.

The labor-saving coup of sit-ups in the senior high school entrance examination is as follows: First, cooperate with breathing: reducing stomach needs to cooperate with breathing, and the muscles of the lower abdomen will become tight to achieve the effect of reducing stomach. When practicing: exhale in the ascending state (when exerting force) and inhale in the retreating state. Be still, for example, keep an angle of 45 degrees, keep normal chest breathing, and don't hold your breath. Usually: Abdominal breathing helps to tighten the transverse abdominal muscles. When inhaling, feel the abdominal cavity lift inward and upward, and exhale deeply after inhaling fully. When you sit, stand or walk, you can consciously take abdominal breathing and form a habit.

Second, don't hold your head with your hands: according to the normal understanding, when doing sit-ups, put your hands behind your head, and then use your hands to drive your body up when sitting up. Although this is very scientific, it is easy to cause neck strain and the exercise effect will be reduced. So when we do sit-ups, we can put our hands on our chest.

Third, the height of getting up: keep a 45-degree angle: Many people blindly think that the higher they get up when doing sit-ups, the better the exercise effect will be. Actually, this is not right. When we get up, we only need to keep a 45-degree angle, so that the abdomen can be squeezed better and the slimming effect is better.
