I would've expected the opposite on the exercise. An hour isn't a lot of time to exercise (just a 'healthy' amount for an average person) but fats usually seem to think it's crazy. "Training" makes it sound like she's mad the sister is "working so hard" (because working hard/not being lazy is seemingly against HAES code). My guess is she goes for a walk/bike ride/jog or lifts 5lb weights in her spare time.
