Studies increasingly show that running is not bad for your knees and runners in fact have some of the strongest healthiest knees around. User proper form, replace your shoes regularly, don’t train for the olympics, and running will be just fine for your joints.
> Studies have shown that recreational runners have a knee and hip osteoarthritis (OA) prevalence that is three times lower than that of sedentary non-runners. Competitive runners showed an even more impressive four-fold reduction in knee and hip OA prevalence. These results are due to the fact that regular running strengthens the muscles around the knee joint and supports overall joint health. Running also plays a vital role in maintaining healthy cartilage and bone density, which are crucial for knee function.
