Maybe you already know this feeling. You wake up tired in a way sleep did not fix. Your low back feels braced even when you have not done anything to strain it. You take a breath and it catches somewhere before it reaches the bottom of your lungs. You cannot point to when it started. It just lives there.
If you have been following this series, you know I have been building toward this moment: not just understanding the psoas, but actually working with it. So today I am giving you the full practice, along with what it is doing, and what you might feel while you do it.
A quick note on the science
The psoas is the only muscle in the body that connects directly to the spine, the diaphragm, and the legs, running from the lumbar vertebrae through the pelvis to the top of the femur. It sits next to the sympathetic chain ganglia and shares fascial connections with the diaphragm through the crura, and it is one of the first muscles to contract in a startle response.
The idea that the psoas “stores” emotional trauma is popular in somatic and yoga communities, and it comes from a real place. Stephen Porges’ polyvagal theory gives us a framework for why a chronically braced psoas and a nervous system stuck in fight, flight, or freeze tend to show up together. What the research does not yet show is a direct, measurable mechanism by which a specific memory gets lodged in muscle tissue. That claim outpaces the current evidence.
What is well supported is this: chronic stress keeps the psoas in a shortened, guarded state, that guarding reinforces a sympathetic-dominant nervous system, and deliberately working with the psoas through breath and slow movement can measurably shift you toward a parasympathetic, safe state. You do not need the trauma-storage claim to be literally true for this work to matter. You just need a psoas that has been holding tension for years and a nervous system ready to be told it can stand down.
Before you start
Every exercise below works because of the pairing of slow movement with breath, not because of the movement alone. Move at a pace where you could comfortably talk. Some of what comes up may be physical, some may be emotional, and both are normal. But if anything feels sharp, numb, or panicky rather than releasing, that is your signal to stop and return to just the breath. This is regulation work, not a stretch you push through, and you are always allowed to do less than what is written here.
One exercise in this sequence, the tremor release, is worth reading about before you decide whether it is right for you today. I have flagged it clearly when you get there.
1. Constructive Rest Position (the foundation)
Purpose: This position takes the psoas out of active work for the first time all day. Most of us are shortening it constantly through sitting, driving, and scrolling. Removing the demand lets it begin to lengthen passively, and it gives your nervous system a few minutes without a job to do.
Lie on your back, knees bent, feet flat on the floor about hip width apart, arms resting wherever they feel supported. Let your low back settle toward the floor without forcing it flat. Stay here for five full minutes.
Breath cue: inhale for a count of four through the nose, letting the belly rise first, then exhale for a count of six. The longer exhale is what shifts you into parasympathetic tone. Do at least ten cycles before moving on.
What you may feel: Restlessness in the first minute or two is common, especially if you are not used to lying still without a phone or a task. Your mind may want to leave before your body does. Stay anyway. Physically, you may notice your low back slowly making more contact with the floor as the minutes pass, or a subtle release through the front of your hips that you were not consciously holding.
2. Psoas March with Breath Lock
Purpose: This teaches the psoas to lengthen with control instead of gripping. The eccentric lowering, the slow part, is where the muscle actually learns to release rather than brace.
Stay in constructive rest. On an exhale, slowly float one knee toward your chest without letting your low back arch or your pelvis tilt. Inhale as you lower it back down with control. Alternate sides, five to eight reps each.
What you may feel: If your low back wants to arch or your pelvis wants to rock, your psoas is compensating for a weak deep core, and that is useful information about your body, not a failure on your part. You may feel mild shaking in the working leg by the last couple reps. That is normal fatigue, not a warning sign, as long as it is not paired with sharp pain in the low back or hip joint.
3. Kneeling Lunge Psoas Stretch, Held with Breath
Purpose: Fascia and a chronically guarded nervous system do not respond to a fifteen second hold. They respond to sustained, breath-led time under gentle tension. This is longer than most stretches you have been taught, on purpose.
Setup:
Start in a kneeling position, then step your right foot forward so you are in a low lunge, right knee bent to about 90 degrees, right knee stacked directly over the right ankle.
Let your left knee rest on the floor behind you. Pad it with a blanket or pillow if your floor is hard.
Bring your torso upright, stacked over your hips, not leaning forward onto your front thigh. Hands can rest on your front knee or come to your hips.
Squeeze your left glute gently and tuck your tailbone slightly under, as if you are tucking a shirt into pants behind you. You should feel the stretch shift from your knee into the front of your left hip and low belly. This tuck is what makes it a psoas stretch instead of a generic lunge, so do not skip it.
Hold and breath: Hold this position for two full minutes on the right leg forward. Breathe in a 4 count inhale through the nose, 6 count exhale through the nose or mouth, for the full two minutes, roughly twelve breath cycles. On each exhale, see if the hip can soften a fraction deeper into the stretch without forcing it.
Then: switch sides. Step your left foot forward, right knee down, and repeat the same two minute hold with the same tailbone tuck and the same breath pattern.
Total for this exercise: two rounds, one per side, four minutes total, roughly twenty four breath cycles combined.
What you may feel: Around the one minute mark, many people notice an urge to shift out of the stretch even though nothing hurts. That is often the nervous system testing whether it is actually safe to stay in a vulnerable, open-hipped position. Staying, within reason, is part of the practice. You may also notice your eyes welling up or a wave of an unplaceable feeling. That can happen when a held position asks the body to stay still longer than it is used to. It is not required to happen, and its absence does not mean you are doing it wrong.
4. Neurogenic Tremor Release
Please read this before deciding whether to do this one today. This exercise intentionally invites involuntary shaking, which is the same mechanism behind Tension and Trauma Releasing Exercises, developed by Dr. David Berceli. It can bring up more than the other exercises in this sequence. If you have an active trauma history you are working through, this is one to do alongside a therapist’s support rather than instead of it, or to skip for now. There is no version of this series where skipping it is the wrong choice for you.
Purpose: The shaking is your body’s own regulatory reflex completing a stress response that got interrupted rather than discharged, rather than something you are generating on purpose.
Setup:
Lie on your back, knees bent, feet flat on the floor, hip width apart, heels roughly a hand’s distance from your glutes.
Press through your feet and lift your hips a few inches off the floor into a shallow bridge. This does not need to be a high lift. A few inches is enough.
Hold this shallow bridge position isometrically, meaning you stay still in the lifted position rather than pulsing up and down.
Timing: Hold the bridge for 60 to 90 seconds, or until your legs naturally start to fatigue and tremble. You are not trying to hold it perfectly still and fight the shake. You are holding it long enough that fatigue starts to set in on its own.
Breath during the hold: Keep breathing normally, a natural rhythm, not held breath. Do not count or control it here. Controlled breath during the shaking phase can dampen the very reflex you are trying to let happen.
Release: Once you feel the trembling start, or once 90 seconds have passed, slowly lower your hips back to the floor. Let your legs fall open slightly, feet still on the floor or legs extended flat, whichever lets the shake continue most easily. Do not tense up to stop it and do not amplify it on purpose. Just let it move at its own pace.
Duration of the tremor phase: Two to three minutes, most people find it starts to naturally taper off somewhere in that window. If it stops sooner, that is complete. If it is still going at three minutes, gently bring it to a close by placing a hand on your belly and taking three slow breaths.
Reps: One round is enough for this exercise. This is not one to repeat multiple times in a single session.
What you may feel: The shaking itself, obviously, usually starting in the legs and sometimes moving up through the hips or torso. Some people feel a wave of relief or lightness afterward. Others feel tired, or notice an emotion surface with no clear story attached to it. Some people feel nothing beyond the physical shake, and that is a complete and normal response too. There is no correct emotional outcome here.
5. Integration: Supported Butterfly
Purpose: This step matters as much as the active work. You are giving your nervous system a chance to register the new state before you stand back up and return to demand.
Setup:
Lie on your back. Bring the soles of your feet together and let your knees fall open to either side, like the wings of a book.
If your hips are tight, place a pillow or folded blanket under each outer thigh so your legs are supported rather than hanging in an unsupported stretch. This is not a flexibility test, so use as much support as you want.
Rest one or both hands on your belly, wherever feels most natural.
Timing: Stay here for five minutes.
Breath: No counting or ratio this time. Just breathe naturally and notice the rise and fall under your hands. If you want a gentle anchor, notice whether your belly is moving more than your chest, which is a sign you have shifted into a calmer breath pattern than when you started.
What you may feel: A kind of quiet that is different from tiredness. Your breath may feel fuller or lower in your belly than it did at the start. Some people feel sleepy here. That is your body telling you it finally believes it is allowed to rest.
What to expect over time
Not a dramatic emotional release every session, though that can happen. More often, people notice they can take a fuller breath, that their low back feels less gripped by evening, or that they fall asleep faster. That is the nervous system doing exactly what it is supposed to do when it finally gets the signal that it is safe to stop bracing.
Do this sequence three to four times a week for it to compound. The psoas did not learn to hold tension in a day, and it will not unlearn it in one either.
This is Signal work in its most literal form: teaching your body that it can come out of alert and into safety. If this is the piece that has been missing for you, it is exactly the terrain we spend real time in during the Root Program. This post is a great place to start.
