If you have tight hamstrings and would like to lengthen this often tight band of muscles, try this yoga posture. Start by standing with a slight bend in your knees. While hinging at the hips, fold forward to touch your toes. If you are unable to touch your toes, feel free to rest your hands on your shins or knees. While maintaining the slight bend in your knees, shift your weight forward a bit toward your toes. This will emphasize the stretch in your hamstrings. Hold the posture for at least 10 breaths.
