In modern society, it is said that the iliopsoas muscles contract and become stiff due to the posture of sitting in a chair for a long time, such as long hours of desk work and long hours of driving, which causes poor posture and causes back pain.

It is buried in the psoas major muscle and works as an auxiliary to the psoas major muscle.

<Iliacus muscle>

Unlike the psoas major muscle, it is a muscle that is not attached to the spine.

The main role is to raise your legs.

<Psoas major muscle>

Among them, the psoas major muscle is said to have a function of stabilizing the spine, and the contraction of the psoas major muscle causes the posture to collapse significantly.

It is said that the posture is distorted, which puts a strain on the lower back and causes back pain.

Another major role of the psoas major muscle is to stabilize the hip joint.

It has been found that the stability of the hip joint allows the foot to be pushed forward more smoothly when walking.

Even in the results conducted by our company in the laboratory of the Department of Sports Science, Osaka University of Health and Sport Sciences, we obtained experimental results such as the change in the leg raising angle due to the relaxation of psoas major muscle tone after using our product.
