Should I Exercise If My Joints Make Noise?

Hi, I’m Kat, a physiotherapist and co-founder of Lake Therapy. If you’ve ever stood up, squatted, or gone upstairs and heard a little pop, crack, or grind in your knees or other joints — you’re definitely not alone. Many people experience joint noises, often worrying they signal damage or arthritis. In most cases, however, those sounds are completely normal and nothing to fear.

If a noisy joint is also painful, our knee pain and shoulder pain pages explain how we help. You might also like protecting your knees at every stage of life.

This phenomenon, known as joint crepitus, can sound unsettling, yet it’s often harmless — especially if there’s no pain involved. Let’s explore what’s really happening when your joints make noise, and how to stay active safely and confidently.

What Exactly Is Joint Crepitus?

Joint crepitus refers to the cracking, grinding, or popping sounds that can occur when you move a joint — commonly in the knees, shoulders, or ankles. These noises can happen at any age but tend to become more noticeable as we get older.

Here are a few common causes:

• Air bubbles – Small gas bubbles can build up within joint fluid and then “pop” as pressure changes, creating that familiar crack.
• Tendon or ligament movement – Sometimes a tendon momentarily slips over a bone and makes a snapping sound.
• Cartilage changes – When cartilage thins (often with age or arthritis), the joint surfaces may rub together more, creating a grinding noise.

The key takeaway? Noise doesn’t always mean damage. In fact, joint crepitus is often just a normal by-product of movement.

When to Be Concerned

In most cases, noisy joints without pain are nothing to worry about. However, if you also experience swelling, sharp pain, stiffness, or instability, it’s worth getting checked by a physiotherapist. These symptoms may indicate irritation, inflammation, or early arthritis that can be managed effectively with tailored treatment.

At Lake Therapy, we often reassure people that crepitus is not necessarily a sign of deterioration — especially if your joint moves freely and comfortably.

Can I Exercise If I Have Joint Crepitus?

Absolutely — and in fact, movement is one of the best ways to support your joints.

Research shows that joint crepitus alone doesn’t reduce function, walking ability, or strength. The challenge often comes from how we feel about the noise. It’s easy to assume that clicking means harm, but this fear can lead people to avoid exercise, which actually worsens stiffness and weakens the supporting muscles.

Instead of avoiding activity, focus on smart, gentle movement. Strengthening the muscles around your joints can improve stability and help the joint glide more smoothly — which may even reduce the sounds you hear.

If a particular exercise causes discomfort, modify it rather than stopping entirely. Sometimes a small change in form or load makes a big difference.

Practical Tips for Exercising Safely

If you have joint crepitus, these simple strategies can help you move with confidence:

• Warm up well – Start with light mobility exercises to prepare your joints.
• Strengthen key muscles – Target surrounding muscles, like the quads for knee support.
• Avoid sudden increases – Gradually build intensity or resistance in your workouts.
• Stay hydrated – Joint fluid depends on good hydration for smooth movement.
• Listen to your body – Occasional noise is fine; persistent pain is not.

Movement truly is medicine — and most of the time, your joints just need to move more, not less.

Your Next Step

Hearing cracks and pops can be unsettling, but most of the time joint crepitus is completely normal. Staying active helps nourish your joints, build strength, and maintain mobility — all key ingredients for long-term joint health.

If joint noise is accompanied by pain or stiffness, or you’re unsure what’s safe, we’d love to help. Together, we can assess what’s happening and create a movement plan that keeps you strong, confident, and pain-free.
