1, cooperate with breathing
Reducing the stomach needs to cooperate with breathing, and the muscles of the lower abdomen will become tight to achieve the effect of reducing the 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.
Slimming principle: This breathing method can ensure that all muscles in the deeper abdomen participate in the work at the same time.
2. Ascending height: keep an angle of 45 degrees.
Sit-ups do not pursue the height of getting up. To understand the correct method, the most correct method should be to extend the duration of the 45-degree angle between the body and the ground, so as to effectively exercise the abdominal muscles. (Duration exceeds 30 seconds)
Generally speaking, sit-ups to lose weight means putting your hands and fingers crossed behind your head.
Don't hold your head with your hands.
In general,' sit-ups' means putting your hands and fingers behind your head, but in the process of sit-ups, you often raise your head with your hands, which is easy to cause neck muscle strain. The correct way is to cross your hands on your chest or put your hands on your ears. When you sit up, let your abdomen exert strength, not your arms.
In addition, the time for doing sit-ups is also particular. Some people who have just exercised their abdominal muscles through sit-ups can't do many sit-ups at a time. You can consider doing 10 sit-ups in each group first, and then increasing the number of sit-ups in each group after training for a period of time to achieve the ideal exercise effect.
