The Psoas; Yoga Asanas to Strengthen and Lengthen with Grace
As a Nurse, I developed a knowledge and understanding of major muscle groups as part of anatomy and physiology, but I have always been fascinated with the psoas muscles and how they impact our general health and strength as they are rarely talked about but have a huge function in our bodies. In addition, since training as a yoga teacher I have been able to develop a further understanding of how yoga practice supports these muscles. Deep in the body, behind the belly and close to the spine, lives a pair of muscles that quietly shape how we stand, walk, breathe, and rest. The psoas muscles do not ask for attention in the way tight shoulders or sore hamstrings do. They speak in subtler ways, through low back tension, short steps, clenched hips, shallow breath, and the feeling that the body cannot fully soften.
In yoga, the psoas is often called the muscles of the soul. It is a poetic name, not a medical diagnosis, but it points to something many people feel in practice. This muscle group sits near the centre of the body, close to the diaphragm, pelvis, lumbar spine, and deep core. When it is overworked, weak, or guarded, the whole inner body can feel drawn inward. When it is strong and spacious, movement often feels lighter, steadier, and more alive.
This post explores the psoas with reverence and practicality. I would like you to get a sense of what these muscles do, how to strengthen them with yoga asanas, how to lengthen them with care, and how to build a balanced practice that feels grounded rather than forced.

The psoas is a bridge between spine, pelvis, and breath
The psoas major begins along the lumbar spine and travels down through the pelvis to attach to the inner upper thigh bone, at a small point called the lesser trochanter. There is one on each side of the body.
Its main jobs include:
Lifting the thigh toward the torso
Helping the spine stay stable
Supporting posture when standing and walking
Influencing pelvic position
Assisting transitions, such as stepping forward from Downward-Facing Dog
Because the psoas connects the spine to the legs, it is involved in nearly every step. It helps you rise from a chair, climb stairs, walk uphill, and balance on one leg.
It also lives close to the diaphragm. This is one reason psoas work can feel deeply emotional or soothing. The relationship between breath, tension, and the deep core is real, even when the language around it becomes symbolic. A held psoas may reflect long hours of sitting, repeated stress, protective bracing, intense training, or simply a lack of varied movement.
A healthy psoas does not need to be endlessly stretched. It needs tone, mobility, warmth, and trust. A weak psoas can feel tight. An overstretched psoas can feel unstable. A guarded psoas may need rest before effort. Yoga gives the body a way to listen before it acts.
How to know when the psoas needs attention
The psoas rarely sends one clear message. It often speaks through patterns. None of these signs prove that the psoas is the only cause, but they can be clues.
You may benefit from psoas-focused yoga if you notice:
Tightness at the front of the hip after sitting
Low back discomfort when lying flat
A short or restricted stride
Difficulty stepping one foot forward from Downward-Facing Dog
Pinching in the front hip during lunges
A tendency to tuck or arch the pelvis without control
Shallow breathing during core work
Uneven balance between the left and right sides
The goal is not to attack the tight place. The body does not open well under pressure. The better path is to meet the psoas through slow breath, clear alignment, and movements that combine strength with release.
The psoas softens through safety, not force. It strengthens through presence, not strain.
Before any deep stretching, warm the body. Gentle cat-cow, pelvic tilts, slow walking, Sun Salutations, or supported bridge can prepare the hips and spine. A cold psoas often resists. A warmed, respected psoas listens.
Yoga asanas that strengthen the psoas with steadiness
Strengthening the psoas is not about gripping the hip crease or yanking the knee upward. It is about teaching the deep front body to lift, stabilis
e, and coordinate with breath.
Move slowly. If the front of the hip cramps, reduce the range. If the low back grips, soften the ribs and lengthen the tailbone.
Navasana builds deep hip flexor strength
Boat Pose, or Navasana, is one of the clearest yoga shapes for psoas strength. The thighs draw toward the torso while the spine stays long.
To practice:
Sit with knees bent and feet on the floor.
Hold behind the thighs.
Lift the chest without flaring the ribs.
Float one foot, then the other.
Keep knees bent if the low back rounds.
Breathe for 3 to 5 slow breaths.
The psoas works with the abdominals here. If the belly hardens like armor, ease back. Think of the spine rising from the pelvis like a candle flame. Strong does not mean rigid.
For a gentler version, keep toes touching the floor and alternate lifting one knee at a time. This teaches the psoas to work without overwhelm.
Supine knee lifts wake the psoas without drama
Lie on your back with knees bent and feet hip-width apart. Keep the pelvis neutral, with the natural curve of the low back present but not exaggerated.
On an exhale, lift one knee toward the chest to about a right angle. On an inhale, place the foot down. Switch sides.
Practice 6 to 10 rounds.
This small movement is humble, yet powerful. It reveals whether the psoas can lift the leg without the low back taking over. Place one hand on the lower belly and one on the front hip. Feel for a smooth, quiet lift rather than a sudden tug.
Plank knee to chest connects psoas to the whole body
From Plank Pose, press the floor away. Draw the front ribs in and lengthen the back of the neck. On an exhale, bring the right knee toward the chest. Pause for one breath, then step back. Switch sides.
This strengthens the psoas in a more active, integrated way. The hip flexor has to work while the shoulders, abdominals, and legs support the whole shape.
Keep the pelvis steady. If the hips hike or the low back sags, take the movement from hands and knees instead.
Standing knee lift trains balance and grace
Stand tall in Mountain Pose. Shift weight into the left foot. Lift the right knee toward hip height, or lower if needed. Keep the standing leg strong, the breath steady, and the face soft.
Hold for 3 breaths, then switch.
This pose may look simple, but it teaches the psoas to work in daily life. Walking is a dance of one leg lifting while the other supports. Standing knee lifts refine that dance.
For added awareness, place the lifted foot against a wall or hold a strap around the thigh. The point is control, not height.
Asana | Main psoas action | Gentle cue |
Navasana | Strengthens hip flexion | Lift the chest before lifting the feet |
Supine knee lifts | Builds controlled activation | Move slowly and keep the pelvis quiet |
Plank knee to chest | Strengthens in a full-body pattern | Exhale as the knee draws in |
Standing knee lift | Trains balance and gait | Root down before lifting up |
Yoga asanas that lengthen the psoas without force
A lengthened psoas is not one that has been pulled into submission. It is one that feels safe enough to release. In yoga, this comes from breath, support, and patience.
The front of the back leg is usually where psoas lengthening is felt in lunges and backbends. Keep the pelvis balanced. If the low back collapses, the psoas may not be lengthening well. It may simply be avoiding the stretch.
Anjaneyasana offers a tender front-body opening
Low Lunge, or Anjaneyasana, is a classic psoas lengthener.
From hands and knees, step the right foot forward between the hands. Slide the left knee back until you feel a gentle stretch through the front of the left hip. Untuck or tuck the back toes, whichever feels better for your knee. Place padding under the back knee if needed.
Bring hands to the front thigh or blocks. Lengthen the tailbone down. Lift the low belly slightly. Let the chest rise.
Stay for 5 to 8 breaths.
The most common mistake is sinking heavily into the low back. Instead, imagine the back hip descending while the spine grows upward. This turns the pose from a collapse into an offering.
Warrior I strengthens and lengthens at once
Warrior I asks the back-leg psoas to lengthen while the body remains strong. Step one foot forward and one foot back. Turn the back heel down at a comfortable angle. Bend the front knee. Lift the torso.
Rather than forcing the hips to square perfectly, give them room. The pelvis is not a trophy. It is a living bowl. Let it face forward as much as your body allows while keeping the low back spacious.
Reach the arms overhead only if the ribs can stay soft. If the breath becomes strained, place hands at the heart.
Warrior I teaches an important truth: the psoas does not need only softness. It needs length with support.
Supported Bridge gives the front hips permission to soften
Setu Bandha Sarvangasana, or Bridge Pose, can be active or restorative. For psoas release, try a supported version.
Lie on your back with knees bent. Lift the hips and place a block on its lowest or middle height under the sacrum, not under the low back. Let the pelvis rest. Keep knees bent, or extend one leg long if that feels good in the front hip.
Stay for 1 to 3 minutes, breathing softly.
This shape gently opens the front body without the demand of a lunge. It is a beautiful choice for tired days, after travel, or after long sitting.
Supta Virasana requires respect and support
Reclined Hero Pose can lengthen the front thighs and hip flexors, but it is not for every body. Knees, ankles, and low backs vary. Use props generously.
Sit between the heels on blocks or a bolster. If that already feels intense, stay upright. If comfortable, recline onto a bolster behind you. Keep the knees no wider than is natural for your joints, and stop if there is knee pain.
This pose is less about achieving a shape and more about surrendering into support. The psoas does not release because the pose is dramatic. It releases because the nervous system believes it is safe.
A graceful psoas practice for strength and length
The psoas loves rhythm. Too much stretching can leave it unstable. Too much strengthening can make it grip. A balanced sequence includes warming, activation, lengthening, and rest.
Try this short practice:
Constructive rest
Lie on your back with knees bent and feet on the floor. Rest for 2 minutes. Feel the back body widen.
Pelvic tilts
Rock the pelvis slowly for 8 rounds. Notice the relationship between low back, sacrum, and breath.
Supine knee lifts
Practice 6 lifts on each side. Move like the leg is floating.
Cat-cow
Warm the spine for 5 to 8 rounds.
Low Lunge
Hold each side for 5 breaths. Keep the pelvis supported and the breath easy.
Plank knee to chest
Practice 3 rounds per side. Use hands and knees if needed.
Warrior I
Hold each side for 5 breaths. Feel strength rising through the legs.
Supported Bridge
Rest for 1 to 3 minutes.
Savasana
Place a bolster or pillow under the knees. Let the belly soften.
This type of practice honors the psoas as both physical and poetic. It does not rush the body toward a finish line. It invites the deepest layers to take part.
Let the psoas become a place of listening
The psoas asks for a different kind of attention. It is deep, old in its function, and woven into walking, breathing, standing, bracing, and resting. To practice with it is to practice with the center of the body, the place where instinct and posture meet.
Some days, the psoas needs fire. Boat Pose, standing knee lifts, and plank variations can remind it of its strength. Other days, it needs sweetness. Low Lunge, Supported Bridge, and quiet breath can remind it that it does not have to hold the body alone.
Approach this work with patience. Let sensation be clear but not sharp. Let the breath stay close. Let strength and softness take turns guiding the way.
When the psoas is strong and spacious, movement can feel less like effort and more like return. The spine rises with dignity. The pelvis settles. The legs swing forward with trust. Somewhere deep inside, the body remembers that grace is not something added from the outside. It is something uncovered, one breath and one honest movement at a time.
