Hip Flexor Pain: What Causes It and How to Relieve It

If you run, lift, cycle, train hard, or sit at a desk all day, you’ve probably felt that deep, annoying tightness at the front of your hips. Sometimes it feels like a dull ache. Sometimes it feels sharp when you lift your leg, walk uphill, squat, or stand up after sitting for too long.

That discomfort is often linked to your hip flexors — a group of muscles that help you walk, run, bend, stabilise your pelvis, and move with power.

At Somabody, we create targeted recovery tools designed to help release tension, support mobility, and make daily recovery easier. If your hips feel locked up, understanding what’s causing the issue is the first step to moving better.

What Are the Hip Flexors?

Your hip flexors are a group of muscles that help lift your knee toward your body and stabilise your pelvis during movement. Two of the most important muscles in this group are the psoas major and iliacus, which together are often referred to as the iliopsoas.

The psoas is especially important because it sits deep in the body, connecting the lower spine through the pelvis to the femur. When it gets tight or irritated, the discomfort can show up in more than just the front of the hip.

Common signs of tight or irritated hip flexors include:

• A deep ache or tightness at the front of the hip
• Groin discomfort during walking, running, or lifting the knee
• Stiff hips after sitting for long periods
• Reduced range of motion during squats, lunges, or running
• Lower back tightness that keeps coming back

What Causes Hip Flexor Pain?

Hip flexor pain can build slowly over time or flare up after training. The most common causes usually come down to a mix of tightness, weakness, overuse, and poor movement patterns.

1. Sitting for Long Periods

When you sit, your hip flexors stay in a shortened position. Do that for hours every day and they can become tight, overactive, and harder to fully lengthen when you stand, walk, or train.

This is why so many people feel stiff through the front of the hips after work, travel, driving, or long study sessions.

2. Running, Cycling, HIIT, or Heavy Training

Repetitive movement can overload the hip flexors, especially if your recovery isn’t keeping up with your training. Runners, cyclists, gym-goers, and field sport athletes often feel this as tightness through the front of the hip or discomfort when lifting the knee.

3. Weak Glutes or Core Muscles

Your glutes and core are meant to stabilise your pelvis and support efficient movement. When they aren’t doing enough of the work, the hip flexors can start compensating. Over time, that can create tension, fatigue, and discomfort.

4. Poor Mobility or Technique

Limited hip mobility can change the way you squat, lunge, run, or hinge. If your hips can’t move freely, your body finds a workaround — and the hip flexors often pay the price.

How to Relieve Hip Flexor Pain

The goal isn’t just to stretch harder. For lasting relief, you want to release tight tissue, restore mobility, strengthen the muscles around the hips, and reduce the daily habits that keep the hip flexors locked up.

1. Use Targeted Deep Tissue Release

The psoas is a deep muscle, which makes it difficult to reach with a standard foam roller. Foam rollers are great for broad areas like the quads and calves, but they’re often too blunt to effectively target deeper hip flexor tension.

The Somabody Psoas Peak is designed to apply focused pressure into the deep hip flexor and psoas area, helping you release tension that standard rollers often miss. Its shape mimics the feeling of a therapist’s elbow or hand, giving you more direct access to tight tissue at home.

Use it before stretching, after training, or as part of your evening recovery routine. Even a few minutes of targeted release can help your hips feel less restricted and more ready to move.

2. Add Hip Flexor Mobility Work

Once the tissue has started to release, mobility work can help restore range of motion. A few simple movements to include are:

• Kneeling hip flexor stretch — gently tuck the pelvis, keep the ribs down, and hold for 60–90 seconds per side.
• 90/90 hip switches — useful for improving internal and external hip rotation.
• Dynamic lunges — ideal before training to warm up the hips and legs.

For best results, use the Psoas Peak before stretching. Releasing the deeper tension first can make your stretches feel more effective and less forced.

3. Strengthen the Glutes and Core

If your hip flexors are always doing extra work, stretching alone probably won’t solve the issue. Strengthening the muscles that support your pelvis can help reduce the load on your hip flexors over time.

Helpful exercises include:

• Glute bridges and single-leg glute bridges
• Bulgarian split squats
• Dead bugs
• Side planks
• Controlled step-ups

Start slow and focus on control. The goal is to build strength and stability, not to push through pain.

4. Break Up Long Periods of Sitting

If you spend most of the day seated, your recovery routine needs to work against that. Try standing, walking, or lightly stretching for a few minutes every hour. It doesn’t need to be complicated — it just needs to be consistent.

Small movement breaks can help stop your hip flexors from staying locked in a shortened position all day.

Where the Quads and IT Band Come In

Hip tension doesn’t always come from the psoas alone. The quads, hip flexors, TFL, and IT band area all influence how your hips feel and move. If your quads are tight or overloaded, they can contribute to that same front-of-hip stiffness.

That’s where the Somabody QuadRelease can help. It’s designed for targeted trigger point release through the quads, IT band area, and surrounding tissue that often gets tight from running, lifting, cycling, or sitting.

Used together, the Psoas Peak and QuadRelease can support a more complete hip and lower-body recovery routine.

When to Get Professional Help

Mild hip flexor tightness often improves with consistent recovery, mobility, and strength work. But if your pain is sharp, worsening, caused by an injury, or affecting your ability to walk or train, it’s worth checking in with a physiotherapist or GP.

Don’t keep pushing through pain that isn’t improving. The right support can help you understand whether the issue is muscular tightness, tendon irritation, joint-related discomfort, or something else.
