Why Your Knees Hurt When You Run—And How to Fix It

The RunRX Podcast

Is running bad for your knees? Absolutely not. In this episode, Coaches Valerie and Caroline unpack one of the most harmful myths in running—that knee pain is inevitable. You’ll learn why most runners are unknowingly locking their knees and how this one habit leads to injury, discomfort, and even giving up the sport altogether.

Discover the real reason your knees hurt when you run—and what you can do about it starting today.

🔑 Key Takeaways:

• ✅ Why locked knees—not running—cause joint pain
• ✅ How keeping your knees bent reduces impact and prevents injury
• ✅ Why phrases like “push off,” “toe-off,” and “foot strike” are misleading
• ✅ The truth about heel striking and how it affects your entire body
• ✅ What elite athletes do naturally that most runners misunderstand
• ✅ How to retrain your standing, walking, and running posture to run pain free

💡 Most runners don’t need more stretching or new shoes—they need better movement patterns. At RunRX, we teach you how to run the right way so you can run for life.
