Psoas pain typically responds well to a combination of targeted stretching, strengthening, and habit changes, with most people seeing significant improvement within one to two months. The psoas is a deep core muscle that runs from your lower spine to your upper thigh bone, and it plays a central role in walking, standing, sitting, and stabilizing your lower back. When it’s tight, weak, or irritated, you’ll usually feel it as a deep ache in your groin, front of your hip, or lower back.
Why the Psoas Causes So Much Trouble
The psoas major attaches along the sides of your lower spine (from your lowest rib area down through four lumbar vertebrae) and runs deep through your pelvis to connect at the inner upper thigh bone. It’s one of the primary muscles responsible for lifting your leg, and it also stabilizes your spine every time you sit upright. This dual role is exactly why it’s so vulnerable to problems: it’s working whether you’re moving or sitting still.
Prolonged sitting is the most common culprit. When you sit for hours, the psoas stays in a shortened position. Over time, it adapts to that shortened length and pulls on your lower spine and hip when you finally stand up. Runners and athletes who do a lot of kicking, sprinting, or cycling are also prone to psoas irritation because the muscle handles enormous loads during repetitive hip flexion. The psoas also shares connective tissue with the diaphragm, your primary breathing muscle, which means chronic stress and shallow breathing patterns can contribute to tension in the area.
How to Tell If It’s Your Psoas
Psoas pain usually shows up as a deep ache in the front of the hip or groin that gets worse when you lift your knee, climb stairs, or stand up after sitting for a while. Some people also feel it in the lower back, since the muscle attaches directly to the lumbar spine. A classic sign is stiffness when you first stand up that gradually eases as you walk around.
You can check for psoas tightness at home using a version of the Thomas test. Lie on your back at the edge of a bed or table. Pull one knee to your chest and hold it there. Let the other leg hang relaxed off the edge. If that hanging leg rises up instead of dropping flat (or close to flat), your hip flexors on that side are likely tight. Repeat on the other side to compare.
Psoas Pain vs. Hip Labral Tears
Psoas problems and hip labral tears both cause groin and front-of-hip pain, which makes them easy to confuse. One distinguishing feature: psoas pain tends to flare with resisted hip flexion (pushing your knee up against resistance) and with passive extension of the hip (stretching backward). You may also feel a specific tender spot when pressing deeply into the front of the hip crease. Labral tears, on the other hand, are more commonly provoked by bringing the hip into flexion combined with inward rotation. Labral tears are also frequently associated with a catching or clicking sensation inside the joint and are usually linked to structural bony changes visible on imaging. If your pain doesn’t improve with the strategies below after several weeks, or if you notice clicking deep in the joint, imaging may be worthwhile.
Stretches That Target the Psoas
Stretching a tight psoas requires getting the hip into extension, the opposite of the flexed position it’s stuck in during sitting. The key is to start gently and progress gradually. Aggressive stretching on an irritated psoas can make things worse.
The half-kneeling hip flexor stretch is the most direct approach. Kneel on one knee with the other foot flat on the floor in front of you, like a lunge position. Keep your torso upright and gently shift your weight forward until you feel a stretch deep in the front of the hip on the kneeling side. Hold for 20 to 30 seconds, then switch sides. To deepen the stretch, squeeze the glute on the kneeling side, which helps the psoas relax through a principle called reciprocal inhibition.
A table or bed edge stretch also works well. Lie on your back at the edge of a bed so one leg can hang off the side. Pull the opposite knee to your chest while letting the hanging leg drop toward the floor. Gravity does the work. Hold for several seconds and repeat on the other side. This is essentially the Thomas test position repurposed as a stretch, and it’s especially useful if kneeling is uncomfortable.
Standing marches serve as a gentle dynamic warm-up for the psoas. Stand with feet shoulder-width apart, lift one knee while pointing your toes down, hold for a few seconds, then lower and repeat on the other side. This gets blood flowing to the muscle without forcing it into end-range positions.
Strengthening a Weak Psoas
Stretching alone won’t fix the problem if the psoas is weak or deconditioned. A muscle that’s both tight and weak is common, especially in people who sit most of the day. The psoas shortens from the sustained position but loses its ability to generate force through a full range of motion.
Eccentric strengthening, where you slowly control a movement against resistance rather than powering through it, has shown strong results for psoas rehabilitation. One effective approach uses a resistance band. Lie on your side with a band attached to your ankle and anchored behind you at about knee height. Start with your hip fully flexed (knee toward chest, knee bent). Slowly extend the hip backward against the band’s pull for a count of three, then quickly return to the starting position for a count of one. Keeping the knee bent throughout isolates the psoas and reduces contribution from the large quadriceps muscle on the front of the thigh.
A rehabilitation case study using this protocol prescribed 3 sets of 15 repetitions, twice daily, over 12 weeks. The band resistance was increased as pain decreased. Some discomfort during the exercise is expected with tendon-related psoas problems, but it shouldn’t exceed moderate levels. If the exercise causes sharp or worsening pain afterward, reduce the resistance or range of motion.
Supine marching is a simpler starting point if the band exercise feels too advanced. Lie on your back with knees bent and feet flat. Slowly lift one foot off the ground by flexing the hip, hold briefly, then lower with control. Focus on keeping your lower back pressed into the floor throughout, which prevents the psoas from pulling the spine into an arch.
Daily Habits That Speed Recovery
Exercise and stretching matter, but what you do the other 23 hours of the day matters more. If you sit for work, set a timer to stand up and move every 45 to 60 minutes. Even a brief walk or a few standing marches resets the muscle’s resting length and improves blood flow. The same applies to long drives: take stops to stretch your hip flexors.
Sleep position also plays a role. Sleeping in the fetal position keeps the psoas shortened all night. If you’re a side sleeper, placing a pillow between your knees can help keep the hips in a more neutral alignment. Back sleepers can try a pillow under the knees to reduce the pull on the lower spine.
Because the psoas shares fascial connections with the diaphragm, diaphragmatic breathing can help release tension in the area. Lie on your back with knees bent and practice breathing deeply into your belly rather than your chest. This isn’t a substitute for stretching and strengthening, but it’s a useful complement, especially if stress or anxiety tends to make your symptoms worse.
What Recovery Looks Like
Most people recover from psoas syndrome within one to two months with consistent physical therapy or self-directed rehabilitation. Pain typically starts improving within the first few weeks as the muscle loosens and strengthens, though full recovery of function, especially for athletes, takes longer. The timeline depends heavily on how long the problem has been building. Someone with a few weeks of tightness after a long road trip will bounce back faster than someone who’s had chronic groin pain for a year.
If stretching and strengthening haven’t meaningfully reduced your pain after six to eight weeks, or if the pain is severe enough to limit walking, a guided injection into the psoas bursa (a small fluid-filled sac near the tendon) is one option. In one study, patients who received this type of injection saw average pain scores drop from 6.4 to 2.9 on a 10-point scale, and 77% experienced meaningful relief without needing any further surgical procedure. About 30% needed a second injection roughly eight months later for recurring symptoms. Injections aren’t a first-line fix, but they’re effective when conservative measures plateau.
A Note on Manual Psoas Release
You’ll find plenty of videos showing people digging a ball or their fingers into the abdomen to “release” the psoas. Be cautious with this. The psoas sits deep in the abdomen, and the area around it contains major nerves (including the femoral nerve), blood vessels, and the sympathetic nervous system chain. There’s significant anatomical variation from person to person in how these structures are arranged. Gentle, gradual pressure from a skilled practitioner can be helpful, but aggressive self-massage in this area carries real risk of nerve irritation or vascular compression. If you want manual work on the psoas, it’s worth seeing a physical therapist or massage therapist who has specific training in this area rather than improvising at home.
