Stand upright with your feet well apart. Allow your arms to hang loosely by your side. You are now ready to commence the exercise. Bend forward and run your fingers down your legs as far as you can comfortably reach. Return immediately to the upright standing position. 

Each time you repeat this movement cycle, you must try to bend down a little further so that in the end you have reached the maximum possible degree of flexion and your fingertips are as close as possible to the floor.

Exercise should only be commenced after the completion of two weeks of practice of Flexion Exercise in sitting, whether Flexion Exercise in sitting has been successful or not in reducing your stiffness or pain. In the beginning, you must do only five or six repetitions per session; the sessions are to be repeated once or twice per day. For a period of three months from the time you have become pain-free, this exercise must never be performed in the first four hours of your day.
