The concept of “Kyokotsu” is already mentioned in numerous posts on this blog. The Kyokotsu movement is part of the entire body movement and cannot be separated from it. There are several basic kyokotsu movements, and these movements are embedded in different exercises already covered in this blog.
The Kyokotsu control consists of several basic movements:
- In and out (horizontally)
- Up and down (vertically)
- left and right (horizontally)
- Figure eight (combination of 1-3 with turning torso
- ……
Those movements connect Kyokotsu with the abdominal area, the spine and the back muscles, which leads to a whole-body movement.
By controlling the kyokotsu, we control the spinal column and surrounding muscles. Kyokotsu is essentially a part that is hard work to move consciously. If you succeed in doing so, other parts of the skeleton have no alternative but to move with it. An interconnection with the spinal column at the center is created when you succeed after much training. If you try to control your spine directly, you find yourself in tension. We need to use an image of the kyokotsu in motion, and thus the spinal column will have the freedom to move by the surrounding muscles.
Major muscles groups affected by kyokotsu control

Kyokotsu control strengthens the iliac muscle and the major psoas muscle which are attached to the spine. Strengthening these muscles helps the movement of the body to bring power to the hands and legs. Moreover, the intentional movement of Kyokotsu causes the opening of the shoulder blades. This in turn enables the freedom of the upper body, including the ribs, and the suppleness of the arms. In addition, Kyokotsu control affect the movement of the pelvis, which increases the strength and freedom of the lower body.

The latissimus dorsi, which is also connected to the spinal column, is also affected by kyokotsu motion. Especially when the kyokotsu rises with an upward move of the arm.

Of course, the above mentioned muscles are just a part of the necessary muscles needed for the whole body movement.
