Stand up straight on a step facing a wall or supportive surface.
Position a rolled towel on the step.
Walk your feet back so that your heels hang off the edge of the step and the toes of your affected foot are on the towel.
Stand on your affected leg and perform a calf raise, pushing up onto your toes.
Hold this position.
Control the movement as you slowly lower your heel back down over the edge of the step.
Ensure you keep your knee straight throughout the movement.
