Sitting Leg Stretch Sit on the floor with the knees straight but slightly flexed (not locked) and the legs as far apart as possible. Place both hands on the same knee. Slowly slide both hands toward the ankle. Stop if pain is felt, and go no farther than a position that can be held comfortably for 10 seconds. Slowly return to a sitting position. Repeat with the other leg. Do this exercise 10 times for each leg.
