The Quad Stretch is part of the Performance Plus Stretching Series. To perform the stretch, Stand up straight, close to a wall or supportive surface. Bend your knee on the affected leg, taking your heel towards your buttock. Hold onto the top of your foot with your hand, and gently pull your heel closer in towards your buttock, until you feel a stretch in the front of your thigh. Ensure you keep your knees together. Hold this position for 20 seconds and repeat on each leg 3 times..
