The psoas muscle is one of two muscles found on each side of the loin, extending internally from the spinal column to the upper end of the femur. It is the deepest muscle in the core and is involved in flexing and rotating the thigh and flexing the trunk on the pelvis. The correct pronunciation of the word psoas has been described as sounding like so-us or so ass.

What You'll Learn
Psoas is pronounced without the 'p'
The psoas muscle is one of two muscles found on each side of the loin, extending internally from the spinal column to the upper end of the femur. It assists in flexing and rotating the thigh and flexing the trunk on the pelvis.
When pronouncing the word "psoas", the "p" at the beginning is silent. Therefore, the word is pronounced as if it starts with an "s" and not a "p". So, the correct pronunciation of the word is "so-as" or "so-ass", and not "poh-as" or "po-ass".
The psoas muscle is often at the root of back problems, and any pronunciation that sounds like "sore ass" is not far from the truth. Sitting for long periods can cause the psoas muscle to shorten, leading to back pain and overstrain on the gluteus maximus.
The psoas is the deepest muscle in the core that connects the spine to the legs. It contracts and releases with every step you take when walking or running.

It sounds like so us
The psoas muscle is pronounced without the "p" at the beginning of the word. So, it sounds like "so + us". Alternatively, you could say it like "so + ass". The psoas muscle is one of two muscles of the abdomen and pelvis that flex the trunk and rotate the thigh. These muscles are the deepest in the core and connect the spine to the legs.
If you sit for long periods, your psoas muscle can shorten, leading to back problems and overstrain on the gluteus maximus. This can cause back compression and further issues. Therefore, any pronunciation that sounds like "sore ass" is not far from the truth!
The psoas muscle is also involved in walking and running, contracting and releasing with each step. You can stretch it by doing a twist or by using a psoas ball.
Some people might find it challenging to pronounce the word "psoas" correctly, and that's okay! Practice makes perfect, and with time and effort, anyone can master the correct pronunciation.

It is one of two muscles of the abdomen and pelvis
The psoas muscle is one of two muscles of the abdomen and pelvis. It is a long, ribbon-shaped muscle that runs from the lower back to the upper end of the femur (thigh bone). There is one psoas muscle on each side of the spine, and they help the body maintain posture and move the legs and hips. The psoas muscle is one of the deepest muscles in the core, connecting the spine to the legs.
The psoas muscle has two segments, one on each side of the body, which assist with lateral and bilateral motions. It combines with the iliacus muscle to form the iliopsoas muscle group in the hip. The iliopsoas muscle is encircled by the dense iliac fascia and is attached to the femur by a common tendon. The psoas muscle has a deep and a superficial segment. The deeper segment originates from the first four lumbar vertebrae, while the superficial segment originates from the lateral surface of the distal thoracic vertebrae and adjacent intervertebral discs.
The psoas muscle is involved in flexing and rotating the thigh and flexing the trunk on the pelvis. It is also involved in the venous and lymphatic drainage of the abdomen, pelvis, and lower limbs. The psoas muscle may influence pelvic floor functions and the balance between pelvic floor movements and the rhythm of the thoracic diaphragm.
Injuries to the psoas muscle are rare due to their location deep inside the body. However, athletes whose sports put a lot of force on their cores or hips are more susceptible to psoas injuries, especially strains. Psoas syndrome is a rare condition that occurs when the psoas muscle is irritated and can cause symptoms similar to arthritis or sacroiliitis. Stretching the psoas muscle can help decrease low back pain and improve hip extension. Excessive sitting can shorten the psoas muscle, causing myofascial pain, low back pain, and difficulty standing.

The psoas muscle flexes the trunk and rotates the thigh
The psoas muscle is a long, ribbon-shaped muscle located in the back, starting at the lower back and running through the pelvis to the top of the femur (thigh bone). There is one psoas muscle on either side of the spine, and they work together to stabilise posture and move the hips and upper legs. The psoas muscle is one of the deepest muscles in the body, and it is essential for correct sitting and standing lumbar posture.
The psoas muscle combines with the iliacus muscle, a large, triangular-shaped muscle that lies over the surface of the ilium, to form the iliopsoas muscle. The iliopsoas muscle is the main flexor of the thigh and is responsible for flexing the trunk and hip and externally rotating the thigh. The iliopsoas muscle group also helps to stabilise the pelvis.
The psoas muscle is a core muscle that plays an important role in back health due to its proximity to the lumbar vertebrae. Nerves in the lumbar spine connect to the psoas muscles and give them sensation. Psoas injuries are rare, but they can cause lower back pain that may radiate to the hips and thighs. Athletes whose sports involve a lot of force on their cores or hips are more susceptible to psoas injuries, especially strains.

Sitting too much can shorten the psoas muscle
The psoas muscle (pronounced "so-as") is one of the most important muscles in the human body. It is one of two muscles that connect the spine to the legs, with one psoas muscle located on each side of the spine, attaching to the top inner aspect of each thigh bone (femur). The psoas is a postural muscle that stimulates blood flow and lymphatic drainage to surrounding organs and tissues, and it even plays a role in enhancing diaphragm function.
Sitting for long periods can have detrimental effects on the body, including the loss of psoas balance. When sitting in a standard chair, the psoas muscle is placed in a shortened position. Over time, this can lead to adaptive shortening, resulting in decreased flexibility, difficulty in properly engaging the psoas, and low back pain. Sitting with hips higher than the knees can also lead to shortening and tightening of the psoas muscle.
To counteract the negative impact of prolonged sitting, active sitting can be practised. This involves using an exercise ball or a specialised chair that allows you to engage your postural and core-stabilising muscles while seated. By introducing active sitting into your workday and daily routine, you can help restore psoas balance and prevent associated issues.
Additionally, specific stretches can be performed to lengthen and strengthen the psoas muscle. One such stretch involves kneeling on the ground with both knees bent and then raising your bottom off your feet. You then plant one foot in front of you while keeping your back straight and your buttock muscles tight as you lean into the planted leg. This stretch should be felt in the front part of the hip on the opposite side. Repeating this stretch with the other foot in front will help target both psoas muscles.
