Quadriceps Stretching Exercises
The quadriceps are four muscles located in the anterior part, or front, or your thigh. This muscle group acts to extend the leg while straightening the knee. Running and biking, as well as daily activities, can result in tight quadricep muscles. Sometimes tightness in your quads may be a culprit in different injuries such a patellofemoral stress syndrome (PFSS) or iliotibial band friction syndrome (ITBS) . Your quads may also be tight if you have spinal stenosis or other related problems with your lumbar spine.
