Why Do My Knees Sound Like Pop Rocks? and What to Do About It

If you’re “grown,” you might have heard your knees crackling like some damn Rice Krispies every time you squat down to pick something up. If you’ve ever asked yourself, “Why can I hear my knees?” you’re not alone. That snap, crackle, and pop has a name: crepitus (boujie word for noisy joints).

The good news is, most of the time, it’s totally normal. The breakdown:

• Gas bubbles: Yea, your knees are basically burping. Tiny bubbles in your joint fluid pop when you move.

• Ligaments + tendons: Sometimes soft tissues snap over bone when you bend or straighten.

• Cartilage changes: As we age or overuse our knees, the smooth cartilage can get a little rough.

• Muscle imbalances: Weak quads or tight hips can make your kneecap track funky, which adds to the noise.

👉 Unless you’ve got pain, swelling, or your knee gives out, those sounds aren’t usually a red flag.

How to Keep Your Knees Cute & Quiet

Here’s the glow-up: strong, balanced muscles around your knees can seriously cut down on the noise. And I’ve got you with a 10-minute daily routine that works wonders, perfect for doing in the morning before work or winding down at night.

Noisy knees aren’t necessarily a sign you’re falling apart. More often, it’s just your body being… well, your body. But keeping your legs strong and flexible will not only turn down the volume but also help your knees age gracefully with you.

So next time your knees start clapping for themselves? Just smile, stretch, and hit that 10-minute flow. Your joints will thank you.
