Nerve Flossing for hamstrings

Start seated on the ground with the bottoms of your feet against the wall, and legs straight. Keeping your back flat lean forward until you feel a stretch in your hamstrings. Keeping your legs and back straight drop your chin to your chest and then look up to the ceiling. Repeat these head motions 5 – 10 times. After every few head tilts see if you can sit further forward without breaking the straight spinal position.
