FITNESS MYTH MONDAY
❌ MYTH: “Running destroys your knees.”
It sounds logical: running puts repeated load through your knees, so eventually they must “wear out,” right?
The research doesn’t support that conclusion for recreational running in generally healthy adults.
🏃 A 2023 systematic review and meta-analysis involving 12,273 participants found no significant difference in the prevalence of knee osteoarthritis between runners and non-running controls.
🦵 Research examining knee cartilage has also found that running can cause small, temporary changes immediately after exercise, but these changes tend to recover toward baseline—not evidence that each run is progressively destroying your cartilage.
Some observational research has even found a lower prevalence of hip and knee osteoarthritis among recreational runners, although that doesn’t prove running itself is protective.
That doesn’t mean every knee problem should be ignored. Previous injuries, training load, recovery, running volume and individual circumstances still matter.
🔥 The takeaway:
Running loads your knees. That doesn’t mean it destroys them.
Progress gradually. Strength train. Recover. And persistent or worsening pain deserves attention—not a “just run through it” mentality.
