There currently is a feature for a coach to "like" (clicking the thumbs up or like button) once a client completes a workout. However, it doesn't appear that a client gets a notification that a coach was cheering them on. In order for them to see this "like" they have to go back to the workout and find it there. Would be great if they got a push notification so they could quickly see that encouragement instead of it getting lost in the notes.
