Methods and systems describe augmenting image content presented on a mirror display. The method includes detecting images of a user in an activity volume in front of the mirror display; the detecting includes identifying a body of the user and tracking movements by the user while in the activity volume. The method includes receiving a request to predict a change in physique of the body of the user, the request includes input parameters that identify a physical exercise and an amount of said physical exercise. The method includes generating an augmented image of the body of the user; the augmented image of the body has said change in physique, the change in physique of the body is assembled from one or more three-dimensional (3D) models of one or more body parts of the body that have been adjusted in shape.
