2. Push-ups can also exercise abdominal muscles. Remember, when you exercise, you must not get tired at once. You must do it in groups to be effective. Generally, you should do about 100 at a time, with at least 5 groups, depending on your own situation.
3. Hold your hands high, your body hangs vertically, your waist and abdomen are lifted hard, and your legs are at 90 degrees to your upper body. Be careful not to shake your body and work in groups.
If there is a lot of abdominal fat, we should insist on aerobic exercise. Running is very effective, which can reduce excess fat and show muscles better.
When exercising, lie prone on the bed, take off the pillow, slowly and forcefully raise your head, so that your head and chest leave the bed surface, at the same time, your knees are straight, and your thighs are forced to leave the bed surface for about 5 seconds, then relax your muscles, lie prone on the bed again, rest for 3-5 seconds as a cycle, and then exercise. Step by step, generally do 20-30 at a time, and practice 1-2 times a day. This method is commonly called "Little Swallow" by doctors.
For people with weak waist muscles or obesity, the above methods are laborious, and some alternative methods can be adopted. For example, it is easier to just raise your head and chest, and don't raise your lower limbs.
It is relatively more acceptable to take the method of "five-point support" for exercise: lie on your back on the bed, bend your knees, press your elbows and back against the bed, lift your abdomen and buttocks upward, support your whole body weight with your shoulders, elbows and feet for about 5 seconds, then relax your waist muscles and rest your hips for 3-5 seconds.
