For most of my running life, I have had issues with Runner’s Knee, pain in my knees caused by my forward muscles being stronger than my side muscles in my legs.

However, most people (like me) make the mistake of not incorporating strength exercises into their workouts and eventually wind up with an injury usually in the knees, hips or calves. Runner’s World magazine has excellent information on injury prevention, stretches and strengthening exercises. Here is one on the knees.
