QUADRICEPS STRETCH
Stand slightly behind and to the side of your chair with your feet hip-width apart (A). Take an exaggerated step forward with one foot so you are in a lunge position. Rest one hand on the chair for support as you bend both knees and lower down further into your lunge (B). Press your back toes into the ground; you should feel the stretch in the front of your back leg up through your hip. Return to the starting position and repeat on the other side.
