Tight Hip Flexors From Sitting: Why It Happens and What Helps

It felt like a lower back problem. I would stretch my back after work and feel better for a few minutes, then the ache would come right back. Part of what I was missing was coming from the front of my hips.

Why Sitting Tightens Your Hip Flexors

When you sit, your hips are bent, which keeps your hip flexors in a shortened position for hours at a time. Muscles adapt to the positions they spend the most time in. When you finally stand up, those muscles can feel tight, and they can tug on your pelvis and lower back.

Common Signs

• Tightness at the front of your hips when you stand up after a long sit.
• Stiff first steps after getting up from your chair.
• A tight lower back that eases when you move around.
• Trouble standing fully upright right after sitting for a long stretch.

What Actually Helps

• Stand up and move regularly. This is the biggest lever. Breaking up long stretches of sitting does more than any single stretch.
• Do a gentle hip flexor stretch. Step into a lunge, tuck your hips under, and hold 30 to 45 seconds per side, a couple of times a day.
• Wake up your glutes. They work together with your hip flexors, and sitting switches them off. A few squeezes or bridges help the pair work the way they should.
• Walk. Walking naturally extends your hips, which is exactly the opposite of sitting.

When to Get It Checked

Tightness is common, but it is not always the cause. If you have sharp pain, numbness or tingling, or pain that does not improve with regular movement over a few weeks, talk to a doctor or physiotherapist.
