What is step-down?

Step down

1. Stand on a single-step footstool. If you do not have a footstool, you can use a thick book, such as a phone book, a dictionary, or an encyclopedia. If you are not steady on your feet, hold on to a chair, counter, or wall while you do this exercise.
2. Slowly step down with your good leg, allowing your heel to lightly touch the floor. As you step down, try to keep your affected knee moving in a straight line toward your middle toe.
3. Move back to the starting position, with both feet on the footstool or book.
4. Repeat 8 to 12 times.
