Seated Hamstring Stretch
Sit on the edge of one chair with one leg straight and resting on another chair of the same or lesser height. Sit up perfectly straight and keep your head up. You can use a towel wrapped around your foot, as shown, to help keep your back straight. Begin to lean forward from your hips KEEPING YOUR BACK STRAIGHT AND HEAD UP until a stretch is felt in the back of your thigh. Maintain this position of stretch for 30 seconds. After 30 seconds, take a deep breath, exhale, and stretch from that position a little further until you feel the stretch a little more into the hamstring region. Maintain this position for 30 seconds. Repeat one more time. Do the same on the other leg
Repeat 3 times a day.
