Systems and methods may use a mobile device communicatively coupled to a wearable device to present an exercise to a user. The systems and methods may modify a therapy calendar, for example, based on information determined from the exercise (e.g., repetitions completed, a duration completed, video, etc.), feedback from the user, or the like. A method may include receiving a control command from a wearable device communicatively coupled to a mobile device, the control command causing an action to be taken by the mobile device related to the exercise. The therapy calendar may be automatically modified, such as in response to determining a number of repetitions or a duration of an exercise. The modified therapy calendar may be presented on a user interface, such as on a display of the wearable device or the mobile device.
