Hi everyone, getting a sharp pain in my left knee after just over 6 miles into a run. It has been suggested that the muscles around the knee are simply not strong enough yet. After a day, the knee is back to normal and Im able to go back out without any probs. can anyone suggest excercises to build up the muscles around that area? Should I be working on quads (squats etc) or are there more targetted excercises to do?
