The Psoas muscle, often referred to as The Muscle of the Soul, is the deepest muscle in the human body. It is responsible for holding us upright and connects our torso to our legs, attaching at the 12th thoracic vertebrae (mid-back) and the 5th lumbar vertebrae (low back) on either side. The Psoas muscle is also linked to our fight or flight response, and when we are stressed or tense, the muscle tightens and shortens, leading to painful conditions like back pain, sciatica, and digestive problems. Releasing tension in the Psoas muscle through specific yoga poses can help to alleviate these issues and improve emotional health.

The psoas muscle is a long, ribbon-shaped muscle in your lower back
The psoas muscle, also referred to as \"The Muscle of the Soul\", is a long, ribbon-shaped muscle located in the lower back. It is the deepest muscle in the human body and plays a crucial role in our structural balance, muscular integrity, flexibility, strength, range of motion, joint mobility, and organ functioning. The psoas muscle connects our torso to our legs, originating from the 12th thoracic vertebrae (mid-back) and the 5th lumbar vertebrae (low back) on both sides, passing through the pelvis, and attaching to the femur (thigh bone).
This muscle is essential for our day-to-day functioning, as it helps to keep us upright and enables us to lift our legs while walking. A tense, restricted, or tight psoas can lead to compensation by other muscle groups, resulting in low back pain, shoulder pain, upper back pain, pelvic pain, and overactive quadriceps muscles. Additionally, the psoas muscle is connected to our diaphragm through connective tissue, influencing our breathing patterns.
The psoas muscle is also intimately linked to our emotional and mental state. It is associated with our \"fight or flight\" response, contracting when we are startled or experiencing mental or emotional stress. A chronically tightened psoas can constrict organs, impair breathing, interfere with fluid movement, and exert pressure on nerves. Furthermore, the psoas muscle is believed to hold onto traumatic experiences at a cellular level. Yoga and specific poses, such as hip openers, can help release tension in the psoas and facilitate the processing and release of trauma responses.
In yoga practices, individuals can focus on poses like Parvottanasana, Prasarita Padottasana, Navasana, and various hand balances to activate and lengthen the psoas muscle. Additionally, backbends are known to energize and lengthen the psoas, providing relief. Constructive Rest is another technique that involves specific positioning and breathing exercises to relax the psoas muscle.
Understanding and caring for the psoas muscle can have significant benefits for both physical and emotional well-being, helping individuals feel more grounded and relaxed while improving their range of motion.

It starts at your lumbar region and runs through your pelvis to the top of your femur
The Psoas muscle, often referred to as the "Muscle of the Soul", is a deep-seated core muscle that connects the lumbar vertebrae to the femur. It is responsible for holding us upright and allowing us to lift our legs when walking. There are two psoas muscles, one on each side of the body, that originate at the 12th thoracic vertebrae (mid-back) and the 5th lumbar vertebrae (low back). From there, the psoas muscles run through the pelvis and insert at the top of the femur (thigh bone).
The psoas muscles are the deepest muscles in the human body and play a crucial role in our structural balance, muscular integrity, flexibility, strength, range of motion, joint mobility, and organ functioning. They are also responsible for flexing the hip joint, such as when bending one knee towards the chest or riding a bike.
A tense, restricted, tight, or neglected psoas can lead to various issues, including low back pain, pelvic pain, and overactive quadriceps muscles. This is because other muscles, such as the back and shoulders, have to work overtime to compensate. The psoas muscles also have a role in breathing as they attach to the diaphragm via connective tissue.
The psoas is intimately involved in our physical and emotional reactions. It is the main muscle of the "fight or flight" response, contracting when we are startled or experiencing mental or emotional stress. A chronically tightened psoas can lead to structural problems, constricted organs, impaired breathing, and pressure on nerves.
Yoga and specific poses, such as hip openers, can help to release tension in the psoas and unlock trauma stored in the body. Relaxing and releasing the tension in the psoas can help to ground us and improve our physical and emotional health.

Psoas injuries are rare but can be caused by sports that put force on the core or hips
The psoas muscle is a long, ribbon-shaped muscle located deep in the body on either side of the spine. It starts at the lower back, just below the ribs, and runs through the pelvis to the top of the femur (thigh bone). It is one of the core muscles in the abdomen and plays a crucial role in maintaining posture and moving the hips and upper legs.
Psoas injuries are indeed rare due to their deep-seated location within the body. However, athletes who participate in sports that exert significant force on the core or hips are more susceptible to psoas injuries. Sports that involve repeated stress on the hips, such as gymnastics, dancing, and track and field (especially high jump and hurdles), can increase the risk of psoas strain or irritation.
Psoas syndrome, a rare condition caused by irritation of the psoas muscle, often occurs without a known cause. It presents with symptoms similar to other more common conditions like arthritis or sacroiliitis, making it challenging to diagnose accurately. Athletes are particularly prone to developing psoas syndrome due to the high-impact nature of their sports.
To prevent psoas injuries, it is essential to incorporate stretching and warming up before any physical activity. Improving flexibility and gradually increasing activity levels can also reduce the risk of psoas strain. Additionally, maintaining a safe and neutral posture during daily activities can help keep the psoas muscles relaxed.
In the event of a suspected psoas injury, it is advisable to consult a healthcare provider, especially if the symptoms persist for an extended period. Rest, anti-inflammatory medication, and tailored stretching programs are often recommended as treatments for psoas impingement and irritation.

The psoas major muscle also has a minor variant, but not everyone has this
The psoas muscle, also referred to as the "muscle of the soul", is a group of two muscles that originate at the 12th thoracic vertebrae (mid-back) and the 5th lumbar vertebrae (low back) on either side. They run through either side of the pelvis and insert at either side of the lesser trochanter of the femur (inner thigh bone at the hip). The psoas muscles are the deepest muscles in the human body and are the only muscles that connect the spine to the legs.
The psoas major muscle is a long fusiform muscle located in the lateral lumbar region between the vertebral column and the brim of the lesser pelvis. It joins the iliacus muscle to form the iliopsoas. The psoas major contributes to flexion in the hip joint. On the lumbar spine, unilateral contraction bends the trunk laterally, while bilateral contraction raises the trunk from its supine position.

The psoas muscle is a stabiliser muscle in your inner core
The psoas muscle is a long, ribbon-shaped muscle that starts in the lower back and runs through the pelvis to the top of the femur (thigh bone). There is one psoas muscle on either side of the spine, and they form the iliopsoas muscle group with the iliacus muscles in the hip. The psoas muscle is a stabiliser muscle in your inner core, connecting your upper body to your lower body by joining your spine to your pelvis and thigh bones.
The psoas muscle plays an important role in back health and helps to stabilise the femoral head within the acetabulum of the hip during the first 15 degrees of movement. It assists with lateral motions (unilateral side contraction) and bilateral motions (both right and left psoas major contractions). For example, unilateral contraction bends the trunk laterally, while bilateral contraction raises the trunk from its supine position. The psoas muscle also helps with flexion and external rotation of the hip, allowing you to flex and move your hips when standing, sitting, or lying down.
The psoas muscle has traditionally been described as having two segments: a deep segment and a superficial segment. The deep 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 lumbar plexus lies between these two layers. The psoas muscle receives blood from the four lumbar arteries from the aorta and small branches of the renal arteries, among other sources.
Psoas injuries are rare due to their location deep inside the body. However, athletes whose sports involve 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 becomes irritated and can cause lower back pain. It is important to see a healthcare provider if you experience lower back pain that does not improve after a week.
