The adductor stretch will help to loosen up your hamstrings. Start by sitting down on the floor. Keep your back nice and straight and make sure that your abs are tight. Your legs should be out in front of you and separated by several feet, depending on what is comfortable for you. Now move your torso forward and place your elbows and forearms on the floor between your legs and rest your abs. Hold the stretch for 20 seconds and then use your abs to sit upright, bringing your legs together again.
