You’re lying on your back doing core exercises or leg raises, feeling good about your workout. Then, right as your leg passes a certain angle, you feel—and sometimes even hear—a distinct CLUNK or CLICK deep inside your hip.
It usually doesn’t hurt, but it feels weird enough to make you pause.
This super common phenomenon is officially known as Snapping Hip Syndrome (or coxa saltans if you want to sound fancy). But what is actually happening in there, and is it something you need to worry about?
What’s Making That Sound?
In the vast majority of cases, a clicking hip isn’t your bones grinding together. It’s actually a tight tendon riding over a bony bump, snapping like a guitar string being plucked.
Depending on where you feel the click, it usually comes down to one of two main culprits:
The Front of the Hip (Internal Snapping): This is the most common type during leg raises or core work. It happens when your iliopsoas tendon (your main hip flexor) glides over the front of your pelvic bone as your leg moves from a bent position to a straight position.
The Outside of the Hip (External Snapping): This happens on the side of your hip, where the IT band or gluteus maximus muscle slides over the outer bony point of your thigh bone (the greater trochanter).
Why Does It Keep Happening?
Tendons don’t snap over bones for no reason. It usually points to a slight imbalance in your movement mechanics:
Overactive Hip Flexors: Sitting for long periods keeps your hip flexors short and tight. When you ask them to work during exercise, they are already under tension.
Underactive Core or Glutes: If your deep core muscles aren’t stabilizing your pelvis, your hip flexors have to pull double duty to lift your leg, making them even tighter.
The Quick Form Fix
Next time you do lower-leg raises or core work, try this subtle adjustment:
Press your lower back flat into the floor BEFORE you lift your legs, and actively squeeze your glutes at the bottom of the movement.
This tilts your pelvis backward, engages your deep core, and changes the angle of the hip joint just enough to prevent the tendon from snapping.
Should You Be Worried?
The golden rule in physical therapy applies here: Noise without pain is just noise.
If the click is totally painless, it’s harmless. However, if the clicking starts to feel sharp, causes an ache in your groin, or makes your hip feel like it’s physically locking up, that means the tendon or joint capsule is getting irritated.
How We Silence the Snap
At SOS PHYSIO, we don’t just tell you to stop doing core exercises. We look at the root cause of the tension. Through targeted manual therapy, we can release tight hip flexors and IT bands, while using precision exercises to wake up your glutes and deep core.
When your pelvis is stable and balanced, your tendons can glide smoothly without making a sound.
