1. Lie flat on the yoga mat, with your feet width apart from your hips, then lie down slowly, slightly retract your chin, lift the bottom of your shoulder blades, put your hands on your abdominal muscles, and slowly roll up your shoulders and torso to make them close to your knees and roll up your upper body. At the highest point of the movement, deliberately squeeze the abdomen extra to achieve full contraction. Then relax, slowly lower, return to the starting position, slowly.

2. If girls want to develop abdominal muscles, they can also choose swimming to develop abdominal muscles, because swimming requires great abdominal exercise. When we swim, our abdomen needs a lot of exercise, and we should swim at least once a week. If you persist for more than half a year, you will basically have abdominal muscles.

Generally we need to do at least 50 sit-ups every day. Generally, a group can do 10. When our ability reaches a certain level, which can be above 100 a day, we will have abdominal muscles after a long time.

4, you can also choose to do push-ups, push-ups can help us develop abdominal muscles, because we need a lot of inhalation and exhalation when doing push-ups, which is very obvious for abdominal exercise. We can do at least 30 push-ups every day, once 10. After a long time, we can have abdominal muscles.

Extended data:

Abdominal muscles are an important part of human connective tissue, including rectus abdominis, oblique abdominis, oblique abdominis and transverse abdominis. When they contract, they can bend and rotate the trunk to prevent the pelvis from leaning forward. Abdominal muscles also play an important role in the activity and stability of lumbar spine, and can also control the activity of pelvis and spine. Abdominal muscle weakness may lead to pelvic forward tilt and increase the physiological curvature of lumbar spine, increasing the chance of low back pain.
