Abdominal muscles include rectus abdominis, oblique external abdominal muscles, oblique internal abdominal muscles and transverse abdominal muscles. 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.

When practicing, I suggest you try standing and lifting dumbbells on one side. The key exercise part is the side abdomen, which can effectively stimulate the muscles on the side of the abdomen and make the waist and abdomen curve more beautiful.

1. Stand with your feet apart and the width should be the same as your shoulders. Hold the dumbbell in one hand and put it on the side or front of your body, and put the other hand on your hips (hold your head up and abdomen in).

2. First lean your body to the dumbbell side, put down the dumbbell, and pay attention to keeping your hips still.

3. Use the strength of the side waist to pull the dumbbell up, keep the hips still and pull it to the other side of the body.

4, each group of 20 times, * * * do three to five times.

Warm reminder: keep your hips stable and your upper body lean to one side. Keep your movements slow and even, and don't rush too fast. Use only the waist to exert force, and relax other parts.
