3 Exercises for the Psoas Muscle

The psoas muscle is one of the most critical yet often neglected muscles in the body. This deep-seated core muscle connects the lower back to the upper thigh, playing a pivotal role in hip flexion, posture, and overall stability. The psoas muscle works in conjunction with the abdominal muscles to provide core stability, which is essential for various movements. Whether you’re walking, running, sitting, or climbing stairs, the psoas muscle is hard at work. However, prolonged sitting, lack of movement, or overuse can lead to tightness, weakness, or imbalance in this muscle, causing discomfort and even chronic pain.

Incorporating exercises that target the psoas into your fitness routine can improve flexibility, strength, and functionality, reducing the risk of pain or injury. Below are three detailed exercises designed to strengthen, stretch, and stabilize the psoas muscle for optimal performance and health.

What is the Psoas Muscle?

The psoas muscle is a deep-seated muscle group that plays a crucial role in maintaining overall mobility and core strength. It is a combination of two muscles: the psoas major and the iliacus. The psoas major originates along the lower spine from the sides of the lumbar vertebrae (L1-L5), and it extends downward through the pelvis. The iliacus originates from the iliac fossa of the pelvis. These muscles join together and attach to the femur (thigh bone), forming the iliopsoas muscle. Functionally, the iliopsoas is a major contributor of flexion of the hip joint.

Psoas Muscle Anatomy and Function

The psoas muscle is a hip flexor muscle that connects to either side of the spine and runs down to the thigh bone. It is approximately 16 inches long. The psoas muscle allows for leg-lifting motions, such as walking upstairs, kicking, or running. The psoas muscle is already strong due to daily activities that use it. However, prolonged periods of sitting can cause the psoas muscle to be placed in a shortened position, leading to stiffness. The psoas muscle is part of the group of muscles known as the hip flexors, which are responsible for hip flexion, the bending of the knee up toward the chest, as well as hip rotation and adduction.

Why Is the Psoas Muscle Important?

The psoas muscle, part of the hip flexor muscles group, has far-reaching effects on both movement and posture. Here’s why keeping it healthy is essential:

• Core Functionality: The psoas connects the upper and lower body, providing critical support for core strength and stability.

• Hip Mobility: It allows for smooth hip flexion, crucial for walking, running, and bending.

• Posture Alignment: A tight or weak psoas can lead to pelvic tilt, poor posture, and lower back discomfort.

• Athletic Performance: Strong psoas muscles enhance explosive movements like sprinting, jumping, and kicking.

• Pain Prevention: A well-conditioned psoas reduces the likelihood of experiencing sciatica, lower back pain, or hip immobility.

Common signs of an unhealthy psoas include:

• Tightness or stiffness in the hips

• Lower back pain

• Poor posture

• Limited range of motion in the hips

• Discomfort during prolonged sitting or standing

Addressing these issues through targeted exercises can significantly improve your quality of life.

Common Causes of Psoas Muscle Tightness

A tight psoas muscle can be caused by various factors, including prolonged sitting, sedentary behavior, and muscle imbalances. When the psoas muscle is too tight, it can tilt the pelvis forward and increase stress on the lower back. This can lead to muscle imbalances that cause pain or hinder the ability to walk. Additionally, a tight psoas muscle can also affect the alignment of the hip joint, preventing it from extending fully, making it difficult to activate the glutes.

Exercise 1: The Bridge

Overview

The Bridge is an effective exercise to strengthen the psoas muscle and improve hip mobility. It also engages the glutes, lower back, and core, making it a comprehensive lower-body workout.

How to Perform

1. Lie flat on your back with your knees bent and feet flat on the floor, about hip-width apart. Your arms should rest comfortably by your sides, palms facing down.

2. Engage your core by drawing your navel toward your spine.

3. Press your heels firmly into the ground and lift your hips toward the ceiling. Your body should form a straight line from your shoulders to your knees.

4. Squeeze your glutes and hold the position for 20–30 seconds.

5. Slowly lower your hips back to the ground, maintaining control throughout the movement.

6. Repeat for 10–12 repetitions, performing 2–3 sets.

Key Tips

• Keep your core tight throughout the exercise to avoid over-arching your lower back.

• Focus on lifting your hips using your glutes and psoas rather than momentum.

• Avoid letting your knees splay outward or inward; keep them aligned with your hips.

Benefits

• Strengthens the psoas and surrounding muscles.

• Improves pelvic stability and posture.

• Reduces lower back strain by enhancing core strength.

Modifications

• Beginner: Perform the bridge with a yoga block or small ball between your knees for extra alignment support.

• Advanced: Place a resistance band around your thighs to increase the challenge.

Exercise 2: Standing Hip-Flexion (Knee Raises) for Hip Flexors

Overview

The Standing Hip-Flexion exercise isolates and strengthens the psoas muscle while improving balance and core stability. This functional movement mirrors everyday activities, such as walking or stair climbing, making it effective.

How to Perform

1. Stand tall with your feet hip-width apart, keeping your back straight and core engaged.

2. Slowly lift your right knee toward your chest, forming a 90-degree angle with your hip.

3. Pause for 2–3 seconds at the top, maintaining balance and keeping your upper body upright.

4. Lower your leg back to the starting position.

5. Repeat 10–12 times on one side before switching to the other leg.

6. Complete 2–3 sets per side.

Key Tips

• Avoid leaning backward or arching your lower back; keep your torso stable.

• Engage your core and glutes for added support.

• If balance is an issue, use a wall or chair for light support.

Benefits

• Strengthens the psoas and hip flexors.

• Enhances balance and stability by engaging the core.

• Improves coordination and functional movement patterns.

Modifications

• Beginner: Perform the movement while holding onto a sturdy surface for balance.
