Is your knee bothering you? Have you been performing knee extension exercises lately? This is the machine that you sit on with knees bent over the edge and the pad is on your shin. Then you straighten both legs to strengthen the thigh (quadriceps ) muscles. Unfortunately, this exercise is overused and it creates grinding under the knee cap. So if you are doing this exercise stop, you are better off doing a modified leg press.
