Experts weigh in on some of the biggest myths about health and fitness.
Myth: Running is bad for your knees.
"Running has long been thought to cause damage to the knees from all the pounding you experience with each foot strike,” says Jason Fitzgerald, a 2:39 marathoner and the founder of Strength Running. “But in the past decade, multiple studies have shown that long-time runners have no increased risk of knee damage. And those with a history of knee arthritis don’t have much of a history with running! In fact, running can even be healthy for the knee, promoting cartilage repair in the knee. Of course, we’re talking about moderate running here—if you’re running marathons or workouts at 6:00 mile pace or faster, you could be increasing your risk of knee arthritis.”
