It can be one, riding a bike in the air.
Similarly, we lie on the floor, and then our backs are close to the floor. At this time, we put our hands on both sides of our heads, our arms can be opened and our legs can be lifted slowly. When the author steps on the bicycle slowly in the air, we should lift our upper body when exhaling, and then touch our left knee with our elbow. Hold this position for about two seconds. You can go back to your original position. Then we touch our right knee with our left joint in the same way for two seconds, and then return to the starting position.
And sit-ups.
I believe everyone can do this action, because when I was a child in physical education class, the teacher taught everyone to do sit-ups, so I was simple. Let me talk to you again. First, we must lie on the ground, and then our knees are at 90 degrees. At this point, our feet are flat on the ground, and our legs are shoulder-width apart. First, keep your back close to the ground, and then put your hands across your chest. At this time, we use the strength of the abdomen to put the body.
Plate support is also a way to practice abdominal muscles.
This is very suitable for women to do some flat support, so it is also very useful for exercising abdominal muscles. The way of plate support is very simple. First bend your hands and then support the ground. Walking is perpendicular to our elbow joint, and our feet are on the ground, so that our bodies leave the ground. Be sure to pay attention to our heads, shoulders, backs, hips and legs. It is best to do this action three to five times a day for about 30 seconds each time. Exercise is a very boring thing, so you must choose a way that suits you, and then stick to it, and there will be good results.
