The ideal arm thickness of adult women should be between body length (cm) × 0. 145 ~ 0. 16. If you are 160cm tall, your normal arm size should be between 23 and 23-26cm. You can calculate for yourself, as long as it meets the requirements, it is the fairy arm.

How to practice:

1. Make a preparatory action first ~ present a climbing action, with palms, knees and shoulders the same width! In addition, the body should relax and don't tighten your shoulders around your neck.

2. Then use the strength of the abdomen to slowly lift the calf slightly with the knee as the support point.

3. After completion, slowly spread the strength to the lower abdomen and arms, and then slowly press the upper body to the floor. Don't touch the floor with your chin just because you can't get off ~ (the first time person should not get off. Follow the above instructions, and you will find the feeling after doing it a few more times)

4. When the upper body is close to the floor, you should feel the feeling of arm lacing ~ This up-and-down action lasts 1 min.

5. 1 minute later, slowly press the body and calf to the ground, showing a head-on state, but the arm is still bent on the ground.

6. Immediately after lying flat, lift the upper body upward, adjust breathing to rest the body, and feel the feeling of abdominal lacing! (this action is done in one go! )
