Sit erect with your legs stretched out. Press the right heel against your left perineum. Interlock your left ankle against the right knee. Twist your trunk to the left while lifting the right hand, bent at the elbow. Allow the elbow to rest on the folded left knee. The left hand should be placed a little behind your body, palm resting on the floor. Hold the position for about 15 counts before relaxing. Repeat the same procedure with the other side.
