Filet mignon, also known as the psoas, is a muscle found in the human body that is responsible for various functions, including hip flexion and spine stabilization. In humans, the psoas muscle contributes to the lumbar curve of the lower back by crossing the rim of the pelvis. However, it is important to note that the filet mignon commonly consumed as a steak is derived from the psoas major muscle of a cow. While the steak refers to the muscle in cows, understanding the human psoas is essential for maintaining posture, avoiding back pain, and preventing injuries.

What You'll Learn
Filet mignon is the psoas major muscle
Filet mignon, or tenderloin, is the psoas major muscle of a cow. The psoas major muscle is very different in cows compared to humans. In four-legged animals, the psoas muscle does not touch the pelvis as it extends from the leg to the spine. In contrast, the human psoas muscle is responsible for creating the lumbar curve of the lower back when it crosses the rim of the pelvis, allowing humans to stand upright.
The filet mignon is prized for its tenderness and lack of fat. Unlike other cuts of steak that derive their flavour from the fat marbled within them, the filet mignon is valued for being fat-free. The psoas muscle plays a crucial role in both animals and humans. For example, when a ballet dancer lifts their leg, the psoas muscle works to flex the hip and turn out the leg while supporting the leg's weight against gravity.
In humans, the psoas muscle is essential for maintaining proper posture and body mechanics. A weak or overworked psoas can negatively impact the spine, leading to conditions like scoliosis and increased pressure on the lumbar disks. Additionally, a tight psoas can pull the spine forward, causing excessive arching and tightness in the low back muscles. To prevent or alleviate these issues, it is important to maintain a balanced routine that includes cardiovascular exercise, core strength training, and stretching.
The psoas muscle is also known as the "sway back" muscle, and its health is crucial for overall stability and flexibility. Physical therapists can assess the length and strength of the psoas and provide guidance on managing any related issues. Furthermore, specific exercises like the plank and single-leg bridge can help elongate and strengthen the psoas, improving its function and preventing injury.

The psoas muscle is important for spinal stability
The filet mignon, otherwise known as the psoas major, is a muscle that is important for spinal stability. The psoas muscle is a band of muscle that connects the leg to the spine. In humans, the psoas muscle crosses the pelvis, creating the lumbar curve of the lower back. When the psoas is in balance with the other core muscles, it helps to stabilise the spine. For example, when a ballet dancer lifts their leg, the psoas muscle works to flex the hip and turn out the leg, while simultaneously stabilising the spine and bearing the weight of the leg.
However, if the psoas is stronger than the other core muscles, it can pull the spine forward, leading to hyperextension or excessive arching of the spine. This can put additional pressure on the spinal discs and cause tightening of the low back muscles. Similarly, if one side of the psoas is tighter than the other, it can rotate the vertebra, leading to scoliosis. A tight psoas can also lead to poor posture, altered body mechanics, increased pressure on the lumbar discs, and increased muscle tension and pain in the lower back.
To test if your psoas is tight, lie on your back with your legs straight and hug one knee to your chest. If the psoas is tight, the thigh on the floor will lift up. To prevent a tight psoas from affecting spinal stability, it is important to incorporate core strength and stretching into your routine. Exercises such as planks and single-leg bridges can help to elongate and strengthen the psoas, improving spinal stability.
In summary, the psoas muscle plays a crucial role in spinal stability. When in balance, the psoas helps to stabilise the spine during movements such as leg lifts. However, an overworked or tight psoas can lead to spinal issues such as hyperextension, scoliosis, and increased pressure on the lumbar discs. Therefore, it is important to maintain a balanced routine that includes cardiovascular exercise, core strength, and stretching to promote spinal stability and overall spine health.

The psoas muscle is also used in ballet
The filet mignon is a cut of meat, specifically the psoas major muscle, usually from a cow. The human psoas muscle is very different from that of a cow. In four-legged animals, the psoas does not touch the pelvis, whereas the human psoas is responsible for the lumbar curve of the lower back as it crosses the pelvis.
The psoas muscle is also referred to as the filet mignon of the human body. This muscle is crucial for ballet dancers, as it helps to lift the leg, turn out the leg, and stabilize the spine. When a ballet dancer lifts their leg in a turned-out position, the psoas muscle works to flex the hip and turn out the leg while bearing the leg's full weight against gravity.
A strong and balanced psoas muscle is essential for optimal performance in ballet. If the psoas is stronger than the other core muscles, it can pull the spine forward into hyperextension, resulting in excessive arching and increased pressure on the disks. This can lead to a "sway back" posture, where the abdominals are overstretched, and the gluteal muscles are inhibited, reducing efficiency and performance.
To maintain a healthy psoas muscle, ballet dancers can incorporate cardiovascular exercise, core strength training, and stretching into their routines. Cross-training with Gyrotonic® exercise or Pilates can also help. Additionally, seeking guidance from a qualified instructor and consulting a physical therapist for back pain are recommended steps to take.
In summary, the psoas muscle plays a significant role in ballet, and its health and balance are crucial for spinal stability, posture, and overall performance in ballet dancers.

The human psoas muscle is different from that of four-legged animals
The filet mignon, otherwise known as the tenderloin, is a cut of meat that comes from the psoas major muscle of a cow. Interestingly, the psoas muscle in four-legged animals is very different from the human psoas muscle. In four-legged animals, the psoas muscle does not touch the pelvis as it runs from the leg to the spine. However, in humans, the psoas muscle crosses the pelvis, creating the lumbar curve in the lower back. This structural difference is due to our upright posture and bipedal gait.
The human psoas muscle is a crucial component of our anatomy, contributing to our unique lumbar curve and facilitating various functional movements. It is a deep muscle located in the abdomen and plays a significant role in spinal stability and hip flexion. The psoas muscle is part of the iliopsoas complex, which includes the iliacus muscle and the psoas major and minor muscles. This complex is responsible for the flexion, abduction, and external rotation of the hip joint.
In contrast to four-legged animals, the human psoas muscle has a more complex role due to our upright posture. As we stand and walk upright, the psoas muscle is essential for maintaining balance, core stability, and spinal alignment. It works in conjunction with other core muscles to stabilise the spine and pelvis, preventing excessive arching or lordosis, which can lead to low back pain and decreased performance. A weak or overworked psoas can negatively affect spinal alignment and posture, potentially contributing to conditions like scoliosis.
The psoas muscle is also involved in various functional movements unique to humans. For example, when a ballet dancer lifts their leg in a turned-out position, the psoas muscle works to flex the hip, turn out the leg, and support the leg's weight against gravity. Additionally, during activities like running or jogging, the psoas muscles contract and lengthen with each stride, demonstrating their dynamic involvement in human locomotion.
Understanding the differences between the human psoas muscle and that of four-legged animals highlights the specialised adaptations of our anatomy to suit our upright posture and bipedal gait. The psoas muscle's role in spinal stability, hip flexion, and movement control is unique to humans and contributes to our distinct functional capabilities.

A weak or overworked psoas can cause back pain
Filet mignon is a name given to the psoas muscle, which is located in the hip and core region of the body. This muscle is responsible for flexing the hip and turning out the leg, as well as helping to stabilise the spine. When the psoas is in balance with the other core muscles, it aids in maintaining proper spinal alignment and movement.
However, when the psoas is weak or overworked, it can lead to back pain and other issues. A weak psoas muscle can cause an imbalance in the pelvis and surrounding hip flexors, leading to postural problems such as lumbar lordosis, where the spine is pulled forward into hyperextension or excessive arching. This puts additional pressure on the spinal discs and surrounding muscles, leading to pain and tightness in the low back.
Additionally, an overworked psoas muscle can become tight, causing tension on its connecting tendons and nerves. This tension can result in pain that radiates from the lumbar region into the thoracic and cervical areas, as well as the hips. The tightness can also affect spinal nerve roots, irritating the nerves and causing further discomfort. In some cases, a contracted psoas muscle can lead to compression of the spinal discs and joints, resulting in structural damage, degenerative disc diseases, and even herniation.
Psoas syndrome, caused by overuse of the hips or sports injuries, can lead to pain in the lower back, hips, buttocks, or groin. This pain may spread down the legs and be exacerbated by certain positions or physical activities. It is important to seek professional help for psoas-related back pain, as self-diagnosis can be challenging due to the muscle's location. Treatment options typically include rest and physical therapy, with a focus on changing lifestyle factors to prevent further issues.
