The psoas, also called "muscle of the soul", is the deepest muscle of the muscular system and, in addition, the one that contributes most to stabilize the human body. It helps us maintain balance, joint mobility, range of motion and the correct functioning of the organs located in the abdominal area.

This muscle, which connects the spine and legs, helps us to stand and makes it possible for us to raise our legs so we can walk. A psoas in good condition favors a correct body posture and offers settlement to the internal structure of the body.

Eastern cultures have given it the title of "soul muscle" because of its relationship with the central nervous system , because being connected to the diaphragm, it is related to breathing.

We know that the respiratory rhythm has a bidirectional relationship with our emotional state, so it is constituted as the messenger of our psychological state. It is, therefore, the muscle in charge of helping us oxygenate our mind.

The psoas or "soul muscle" is considered the spokesman of emotions, emotions that manifest both with "butterflies in the stomach" and with "the shrunken stomach".

The tension of the psoas, the affectation of our emotional health

Stress, coupled with the lifestyle that accompanies it, can strain the psoas causing it to shorten or harden. This fact produces pains in the back and lower back, digestive problems, painful menstruations, etc.

If the state of stress becomes chronic, the psoas ends up shortening and hardening, affecting our physical and emotional state, generating a great discomfort that ends up exhausting our body.

On the contrary, the stronger and more flexible the "soul muscle", the more vitality we will emanate , since the energy can flow freely through the holes, the muscles, the joints, the organs, etc.


Exercises to relax the "soul muscle"

To work the flexibility and strengthening of this muscle we can carry out several exercises or stretching. For this we must take into account that, as seen in the images, the muscle begins at vertebra T12, continues through the five lumbar vertebrae, and connects to the upper part of the thigh bone (femur).

Disciplines such as yoga focus on working this muscle, since doing so helps to release unnecessary tension and flow through truly liberating bodily movements that help us reconnect with our needs.

Let's see some of the exercises that allow us to stretch, strengthen and relax the "soul muscle". However, before we begin to define them, we must know that in each position we must maintain ourselves for a few seconds, as well as repeat it with each leg. In addition, we should know that it is advisable to perform daily, being also convenient to do them in the morning.


  • Stand with your legs spread at shoulder length.
  • Keep your back straight, it will help you to contract the abdominal muscles.
  • Take a step forward with the right foot.
  • Lower the left knee to the floor and slide it back until the entire left leg is stretched.
  • Rest your hands on your right knee and hold for a few seconds.
  • Sit up calmly, go back to the beginning and do the same exercise with the other leg.
