First, the skills of sit-ups
When doing sit-ups, you should cooperate with breathing, so that the muscles of the lower abdomen will become tight and achieve the effect of reducing stomach. When sit-ups enter the rising state, you must breathe normally and inhale normally when you retreat. When we keep an angle of 45 degrees, we should still breathe normally in the chest. Never hold your breath. This way of breathing can make your deeper abdominal muscles participate in your work, which is very convenient for everyone to lose weight.
Second, keep an angle of 45 degrees.
Sit-ups don't have to buckle your head on your knees. The higher you get up, the more effective you can be. Correct sit-ups should extend the duration of the included angle between the body and the ground as much as possible, that is to say, keep an angle of 45 degrees, preferably about 30 seconds, so that abdominal muscles can achieve effective practice and sit-ups can achieve results. In addition, when you start to learn sit-ups, your index fingers are crossed behind your head, but in fact, the correct way is to cross your hands on your chest or put your hands on your ears, so that your abdomen can exert strength during sit-ups, instead of using your arms.
Third, sit-up skills
For beginners, the number of sit-ups should not exceed 65,438+00. After each sit-up, you can stand up or lie down for a while and relax your abdominal muscles for more than 65,438+00 minutes. Secondly, the cushion for sit-ups should not be too soft. If it is too soft, it will easily make the waist lose support, make the lumbar spine uncomfortable, and at the same time deform the movement, thus affecting the effect of exercise. If we do sit-ups at home, try to bend our knees 90 degrees to form a step shape. This is the correct starting posture. Roll up your upper body when you do it, not lift it. From 3 pm to 5 pm is the peak period of human metabolism, which is the most suitable time for exercise.
