When you are in a cast long term there is a always the concern of muscle atrophy, so Emma makes it appoint to exercise as much as she can, and her body shows it. She crutches to the park on a warm sunny day in her sports midriff and does a full workout on the various machines minding not to stuff her long exposed casted toes. When the workout is over she crutches over to a bench to prop her leg up and check out her naked toes and see that all is well before crutching home.
