||Slowly bend forward gently putting both hands on the ground close to your feet.
||Lower your buttocks slightly as though you were going to sit in a chair. This will cause the knee to bend. Do not let the knee bend beyond the beyond the length of the foot.
||Straighten the leg as far as you can without hurting or pulling the back leg muscles (hamstrings). Repeat this process 5 - 10 times, depending on the strength and flexibility of your legs.
||Although this exercise is a great leg stressor and very useful, many people may find it too difficult or painful for their knees. This exercise can be modified by slightly bending the knee from a standing position. Simply bend your standing knee as comfortably as possible and then straighten it. Repeat this about 5 - 10 times. If this exercise is too difficult even when standing, please consider it an optional exercise and move onto the next exercise.
