Strengthening exercises can make the muscles tight, so follow strength exercises with stretching exercises. Stretching the muscles that support the knee with knee exercises is also important in preventing injury. Flexible muscles are not as easily injured as tight muscles. Tightness of muscles connected to the knee can also pull the knee out of alignment. When doing stretching exercises, be careful to go slowly and not to overstretch. You do not want to tear a muscle. Increase the duration of your knee exercises gradually to avoid overuse injuries and knee pain. Be patient.
