This image says a lot about why posture is never just stand up straight. Both red lines are the psoas, the same deep muscle on each side of the body, but shown in two very different nervous system states. The psoas links your spine, ribs and pelvis to your legs and is deeply tied to stress, safety and survival. When the nervous system lives in go mode, this muscle stays switched on, pulling the body forward, compressing the chest, altering breathing and changing how we move, sit and even feel. Over time it’s not a posture problem or a tight hip flexor issue, it’s a regulation problem. You don’t stretch this away, you calm it, reconnect it, and give the body a reason to feel safe again. When the nervous system settles, posture follows.

Try this exercise: Lie on your back on the floor with your legs extended. Lift your arms overhead and interlace your fingers, then on an exhale, press your lower back into the floor and simultaneously lift your legs and arms off the ground, creating a full body float. Hold for 3–5 seconds, breathing deep into your belly, then slowly lower. Next, add a gentle twist, as you lift, rotate your legs to the right and arms to the left, then switch sides, like a full-body untwist. This is not just a core exercise, it lights up the nervous system, stretches and releases the psoas dynamically, opens the chest, and reconnects spinal and hip alignment in one smooth movement.

My physical therapist: you can get a deep stretch and muscle release if you lay on a ball in this spot. It might feel...different though

Me: mhmm okay. Sure thanks.

At home, sticks ball near psoas, slowly relaxing against it, "OkaaaaaAAAAAAAYYYYYYAAAAAHHHHHHHHHHHHHH FUUUUUUUAAAAACK!! I CANT MOVE AAAHHHHUUUUHHHH! Hnnnnnn!!!!!!! FUCK WHY DOES IT HURT SO MUCH!!!?? HUUUUUUUUUU kssssssssssss!!!!!"

20 second later, nerves over stimulated, desensitized, muscle relaxed.

Me: -exhausted- why did it feel..like I had came out of surgery again??? That fucking hurt jfc. How was I walking with my muscle like that?!?!

I call this a Single-Leg Elevated Cobra Stretch. It’s like a cross between a regular cobra stretch and a runner’s lunge stretch. — This gets a goooood stretch in the Psoas/hip flexors that I’m unable@to feel in a normal cobra. Keep your chest up for a deeper stretch. — I hold for at least :30 but usually go for closer to 1:30. Be slow getting out of the stretch. This is better done on something less squishy than an ottoman but I work with what I got. . . #bostonfitness #cosplayfitness #psoas #hipflexors #homefitness #homeyoga #selfcare #bodybuidling #mensphysique #stretching #fitnerd #superherotraining #mobility #flexibility (at Boston, Massachusetts) https://www.instagram.com/p/B7GwHtqju9i/?igshid=1kkoz7oos0in2

The hip flexors do not pull the leg forward during swing (mostly).

The hip flexors are not responsible for pulling/flexing the swing leg forward in gait or running. The psoas is a mere swing phase perpetuator, not an initiator. For about 2 decades we have been saying in our lectures, posts and podcasts that it is the reduction of the obliquity of the pelvis during gait from various other tissues and biomechanical events that causes leg swing, meaning the trail leg is brought forward in swing largely by the abdominal muscle linkage to the pelvis (and other loaded tissues) that is responsible for forward swing of the leg. It is not the hip flexor group that does this hip flexion action. Thus it could be considered foolish to train the hip flexors to be the primary swing drivers. Here is another supporting piece of research.

"These experiments also showed that the trailing leg is brought forward during the swing phase without activity in the flexor muscles about the hip joint. This was verified by the absence of EMG activity in the iliacus muscle measured by intramuscular wire electrodes. Instead the strong ligaments restricting hip joint extension are stretched during the first half of the swing phase thereby storing elastic energy, which is released during the last half of the stance phase and accelerating the leg into the swing phase. This is considered an important energy conserving feature of human walking. "

ILIOPSOAS MUSCLE AND FASCIA ILIACA . [ANATOMY LESSON] . @StefanDuell vs. @DrJoeMuscolino . The iliopsoas muscle belongs to the inner hip muscles and is innervated by the femoral nerve + lumbar plexus. It consists of: ▪️Psoas major: origin. from 1st-4th lumbar vertebrae, costal processes of all lumbar vertebrae and 12th thoracic vertebrae + ins. at the lesser trochanter of the femur. ▪️Iliacus: runs from the iliac fossa to the lesser trochanter. The psoas major and iliacus unify in the lateral pelvis shortly before the inguinal ligament becoming the iliopsoas. There they pass below the inguinal ligament through the muscular lacuna together with the femoral nerve (Pic 2,3). Both muscles are completely surrounded by the iliac fascia (Pic 4,5). The lumbar plexus lies dorsally from the psoas major which is penetrated by the genitofemoral nerve. . The iliopsoas is the strongest flexor of the hip joint (important walking muscle). In the supine position it decisively supports the straightening of the upper body (e.g. during sit-ups). Furthermore it rotates the thigh laterally. A unilateral contraction leads to a lateral flexion of the lumbar vertebrae column. It plays a significant role in the movement and stabilization of the pelvis. . In the video you can see a psoas major cadaver dissection: We see the left-sided psoas major, which attaches from T12 all the way to the lesser trochanter of the femur. . The majority of the body lies within the abdominopelvic cavity and is called the abdominopelvic or abdominal belly. When it passes deep to the inguinal ligament, it is the femoral belly. . Seeing the abdominal belly here informs our palpation protocol. First, we must contact the client immediately lateral to the rectus abdominis. But then, visualizing the muscle, we must sink in slowly posteromedially toward the spine. Once we feel the client’s spine deep to soft tissue, we should be on the psoas. So now we ask the client to gently engage it by flexing their thigh at the hip joint and we should feel the psoas palpably harden. . Once located, we can now assess and treat if appropriate. . #Psoas #Iliacus #Iliopsoas #Muscle #Anatomy #Physiotherapy #Osteopathy #Fascia (hier: Indian Wells, California) https://www.instagram.com/p/BuwdaV6A_Lv/?utm_source=ig_tumblr_share&igshid=sns1zpdhs5yj
