I believe that people who are losing weight often hear that the key to building a small waistline lies in the "abdominal oblique muscle"! As a deep core muscle group, the abdominal oblique muscle is hardly used in daily life, so almost every fitness instructor has the experience of asking students how to lose weight. The exercise of abdominal oblique muscle can not only train the waist line, but also help the internal organs to return to their original positions and improve hunchback. "Dong", the online paid fitness teaching center in Japan, pointed out that the abdominal oblique muscle is a deep muscle responsible for stabilizing the trunk and assisting the upper body rotation, and it will be used in daily life. Even the most popular abdominal muscle training, such as persistence and sit-ups, can only train rectus abdominis, so the abdominal oblique muscle is often the key for bodybuilders to really lose weight. The Japanese surgeon Yukio Horida also said that if poor posture leads to hunchback for a long time, the ribs will sag and open, and the internal organs will fall into the lower abdomen, making the stomach bigger. Oblique abdominis is an important muscle to support the ribs and pelvis, so exercising oblique abdominis can also help the ribs and internal organs to return to their original positions, so that the lower abdomen will naturally disappear and the hunchback will disappear. The fitness instructor of the East Pole Sports Oasis has also developed a trick to turn sit-ups for one minute, which can not only train all the muscles of the upper body, but also really adjust the abdominal oblique muscles and adjust the internal organs. The annoying lower abdomen can be eliminated naturally, and a beautiful waist can be created. Turn to sit-ups
