Swing left and right legs
We lie down, put our arms under our shoulders and support ourselves with our hands. Elbows can be slightly bent, legs can be straightened, and the back can be kept straight and the body can be in a straight line. After the body remains stable, one leg sticks out to the side, recovers when the toes touch the ground, and then changes to the other leg. Keep this for a few minutes and do several groups every day. Doing so can effectively reduce abdominal muscles.
Lie on your back and roll your abdomen.
We can lie on our back with our legs slightly bent, our feet on the ground, our upper body close to the ground and our heads in our hands. In fact, this method is a bit similar to sit-ups, except that the legs are bent and the upper body should be lifted by the strength of the abdomen. When you get up, your shoulders should be off the ground first, then your upper back and lower back are away from the ground. When you reach the top, you should keep your body stable, pause a little, and then restore your lower back, upper back and shoulders.
Supine windmill
We can lie flat on the ground, with our upper body on the ground, our arms open at our sides and our legs straight and close together. Then lift your legs with the strength of your abdomen, then rotate to one side of your body until the apex is flat, and then lift your legs and hit the other side of your body.
These three movements can be done 15 times a day, four groups at a time, with a break of about 30 seconds between each group. Don't forget to stretch your abdominal muscles after you finish these caves. If the body fat rate is not enough, you can do aerobic exercise for half an hour after these actions, so that you can have a beautiful vest line soon.
