Psoas Exercises: Release and Strengthen Your Deep Hip Flexor

The psoas (pronounced SO-az) is one of the most important yet misunderstood muscles in the body. This deep hip flexor connects your spine to your legs and plays crucial roles in posture, walking, and core stability. A tight or weak psoas can contribute to low back pain, hip problems, and poor posture. Understanding how to properly care for this muscle can transform your movement quality.

Understanding the Psoas

Full Name: Psoas major (often combined with iliacus and called "iliopsoas")

Location: Deep in the abdomen, running from the lumbar spine to the inner thigh

Origin: Transverse processes and vertebral bodies of T12-L5 (lower spine)

Insertion: Lesser trochanter of the femur (inner upper thigh)

Unique Feature: The only muscle that connects the spine directly to the legs

Functions of the Psoas

• Hip flexion: Primary hip flexor, lifting your thigh toward your torso
• Spinal stabilization: Supports the lumbar spine from the front
• Posture maintenance: Helps maintain the natural lumbar curve
• Walking and running: Initiates the swing phase of gait
• Core integration: Works with deep core muscles for stability

The Psoas and Modern Life

The psoas is often called the "muscle of the soul" because of its connection to the stress response and breathing. In modern life, several factors commonly affect it:

Prolonged Sitting

• Keeps the psoas in a shortened position for hours
• Can lead to chronic tightness
• May contribute to "lower crossed syndrome"

Stress and Tension

• The psoas responds to the fight-or-flight response
• Chronic stress can create chronic psoas tension
• May contribute to anxiety and shallow breathing

Over-Training Hip Flexion

• Too many sit-ups, leg raises, or running without balance
• Can create overdeveloped, tight psoas
• Often accompanied by weak glutes

Signs of Psoas Problems

Tight Psoas:

• Low back pain, especially when standing
• Hip pain at the front of the joint
• Difficulty standing up straight after sitting
• Pain that improves when lying with knees bent

Weak Psoas:

• Difficulty lifting knee to chest
• Low back instability
• Poor single-leg balance
• Compensatory overuse of other hip flexors

Stretches for the Psoas

Half-Kneeling Psoas Stretch (Best Overall)

1. Kneel on one knee, other foot forward
2. Tuck your pelvis under (posterior pelvic tilt)
3. Shift weight forward while maintaining the tuck
4. Reach same-side arm overhead and lean away slightly
5. Hold 45-60 seconds each side
6. Key: The pelvic tuck is essential—without it, you'll stretch other muscles instead

Supine Psoas Stretch

1. Lie on your back at the edge of a bed or bench
2. Let one leg hang off the edge
3. Pull opposite knee to chest
4. Let the hanging leg relax and drop
5. Hold 60 seconds each side

Low Lunge with Reach

1. From half-kneeling, sink deeper into the stretch
2. Reach both arms overhead
3. Side bend away from the back leg
4. Breathe deeply into the stretch
5. Hold 30-45 seconds each side

Constructive Rest Position

1. Lie on your back with knees bent, feet flat
2. Let knees fall together to rest against each other
3. Place hands on belly
4. Breathe deeply for 5-10 minutes
5. This allows the psoas to release passively

Releasing the Psoas

Self-Release with Ball

Caution: The psoas lies deep near important structures. Be gentle.

1. Lie face down with a soft ball (not too firm) placed 2 inches from your navel, toward the hip
2. Relax completely and breathe
3. Allow body weight to provide gentle pressure
4. Hold 60-90 seconds each side
5. Stop if you feel pulsing (you may be on the aorta)

Supported Bridge Release

1. Lie on back, place yoga block under sacrum
2. Let one leg extend long while other knee stays bent
3. Allow the extended leg's psoas to release
4. Breathe deeply for 2-3 minutes each side

Strengthening the Psoas

Supine March

1. Lie on back with knees bent, feet flat
2. Lift one knee toward chest while keeping spine neutral
3. Lower with control, then lift other knee
4. Perform 3 sets of 12 repetitions each leg

Standing Psoas March

1. Stand tall, holding support if needed
2. Lift one knee to 90 degrees
3. Hold 5 seconds
4. Lower with control
5. Perform 3 sets of 10 holds each leg

Hanging Knee Raise (Advanced)

1. Hang from a pull-up bar
2. Raise knees toward chest with control
3. Lower slowly without swinging
4. Perform 3 sets of 8-12 repetitions

Psoas March with Band

1. Loop resistance band around foot
2. Anchor other end low
3. Lift knee against resistance
4. Control the lowering phase
5. Perform 3 sets of 12 repetitions each leg

Dead Bug (Psoas Integration)

1. Lie on back, arms toward ceiling, knees at 90 degrees
2. Lower one arm overhead while extending opposite leg
3. Keep lower back pressed to floor
4. Return and repeat opposite side
5. Perform 3 sets of 10 repetitions each side

Psoas-Focused Movement Practices

Walking with Awareness

1. Walk slowly, focusing on initiating each step from deep in the hip
2. Allow the psoas to lengthen as leg swings back
3. Feel the connection from spine to leg
4. Practice for 5-10 minutes

Supported Backbend

1. Lie over a bolster or rolled blanket placed under mid-back
2. Arms rest out to sides or overhead
3. Allow front body to open
4. Breathe deeply for 3-5 minutes

Balancing the Psoas

A healthy psoas requires balance with:

Glutes

• Often weak when psoas is tight
• Strengthen with bridges, hip thrusts, squats
• The glutes and psoas should work in balance

Core Muscles

• Deep core (transverse abdominis) should work with psoas
• Include planks, dead bugs, and anti-extension exercises

Hip Extensors

• Hamstrings and glutes oppose psoas action
• Include hip extension exercises in your routine

Daily Psoas Care Routine

Morning (5 minutes):

1. Constructive rest position: 2 minutes
2. Half-kneeling stretch: 60 seconds each side

After Sitting (2 minutes):

1. Standing hip flexor stretch: 30 seconds each side
2. Walk around for 1 minute

Evening (5 minutes):

1. Supine psoas stretch: 60 seconds each side
2. Supported bridge release: 2 minutes each side

When to Seek Help

Consult a healthcare provider if you experience:

• Severe or worsening low back pain
• Pain that radiates down your leg
• Numbness or tingling
• Difficulty walking or standing
• Pain that doesn't improve with stretching
• Symptoms after trauma

Common Mistakes

Stretching Without Pelvic Tilt The hip flexor stretch most people do misses the psoas—you must tuck the pelvis.

Over-Releasing The psoas provides important stability. Don't try to completely "turn it off."

Ignoring Strengthening Some people have weak, not tight, psoas. Assessment matters.

Aggressive Self-Release The psoas is near vital structures. Be gentle and cautious.

Summary

The psoas is a powerful, deep muscle that deserves attention in your movement practice. Most people benefit from a combination of gentle stretching (with proper pelvic positioning), occasional release work, and targeted strengthening. Balance your psoas work with glute and core exercises for optimal function. Whether you're dealing with back pain, hip tightness, or simply want to move better, caring for your psoas can make a significant difference in how you feel and function.
