You’ve heard it:  that hollow clunk your hip makes during certain exercises.

It doesn’t hurt, but good lord, it sure doesn’t sound good.

You’ve probably heard that it’s a tight hip flexor muscle or tendon popping over the bone.  The solution must be to stretch your hip flexors, right?  Wrong.

Read on to discover how to go about quieting a popping hip flexor without stretching.

Which Hip Flexor is Popping?

There are a lot of muscles that flex the hip.  For the purposes of this article, we’re narrowing down the hip flexor umbrella to the psoas muscle.

The psoas can be considered part of your core because it attaches to your spine.  There is so much more to your core than just your abdominal muscles!

The psoas is typically tight and weak.  It’s tight because it’s trying to provide stability for another muscle that is not doing it’s job.  The tightness you feel may be a result of an anterior pelvic tilt where the hip flexors pull your pelvis forward and down.

The kicker here is that even though the psoas is tight – it’s weak.  When you massage or stretch a weak muscle it destabilizes.  It becomes weaker.  Your brain was using that muscle as a compensator and you took away your support.

The brain says, “Well that was interesting!  Let’s put that stability back in place, so the body doesn’t collapse.”  Then you get tight all over again.  It’s a vicious circle when you stretch and stretch and never get any results.

So the psoas is the popping hip flexor and needs to be strengthened.


What You Really Need to Stretch

Stretching the hip flexors can worsen the snapping hip.  So it’s important to determine which muscle actually needs to be stretched.

In my case, it was the Quadratus Lumborum (QL, pictured below.)













The QL was overworking for my psoas.

It’s kind of hard to effectively stretch the QL, so massaging it works better.

This is a common pairing, but not the only scenario.  The gluteus maximus could be overworking.  The only way to know for sure is to have your muscles tested.  I can do that for you!


Here’s a little more about my popping hip flexor.

Strengthening the Weak Psoas

I mentioned above that you need to strengthen the weak muscle.  The exercise below is the exact exercise I did for my corrective exercise homework.

Simply do it until you feel fatigue in the crease of your hip.  That’s your psoas saying, “I’m tired.”  The amount of reps will be different for everyone.  Keep your toes turned out.


A popping hip flexor means you’ve got a muscle imbalance.  Please stop thinking that everything that feels tight needs to be stretched.  Figure out why it’s tight.
