Flexuline The athlete hangs on a Swedish wall or horizontal bar, cuts the abs and brings his knees to his chest. It is necessary to ensure that the movement occurs due to the reduction of the press, and not by throwing the legs up. A variation for those who need to use oblique muscles too. To begin with, the usual lifting of the knees to the chest is performed, a person brings the knees rigidly, and then a turn, that is, bringing the knees to one and the other shoulder. The secret of movement is not to relax the abs. It is often called the press in the elbows, but then the athlete would have to make an exit by force, and hang on the horizontal bar on the elbow, which is very difficult. So we will perform correctly - in the forearm. The stand is taken in a special simulator, the shoulder blades are pulled together and lowered to the pelvis, and the back is pressed against the back of the machine. It is also important not to tear off the lumbar, so that the movement is strictly due to the press. Further, according to the usual scheme, either socks are brought to the top of the structure, or hips to the lower ribs. Sometimes the legs are raised only to the midline, but try to control the movement due to the rigid retraction of the abdomen. This is twisting the spine with flexion in the hip joint. Sometimes knee flexion is added. The goal is to work out the entire rectus abdominis muscle. Obliques turn on if you rotate from shoulder to shoulder at the top, and transverse ones if you pull the stomach inward, literally push the abdominal wall to the spine. In dynamics and statics quite a lot of muscles are involved additionally: Tension fascia wide; Rectus muscle of the back.
