Description:Sit with one leg straight out in front and toes pointing upwards. Bring your other foot towards your knee. Let your head fall forward and reach towards your toes with both hands. It's important to keep your toes pointing straight upwards. Letting your toes fall to one side will cause this stretch to put uneven tension on the hamstring muscles. Over an extended period of time, this could lead to a muscle imbalance. Hold the stretch position for a minimum of 20 seconds and then the other leg.(1:23)
