Where exactly did you get that picture from? I want to laugh, but I'm not sure if it's okay to do so. It's like one of those awkward social events where you're not sure if it's a joke or something serious.
But in anycase, to the TC, if you don't feel like going to the gym, then don't go. There's nothing wrong with not going. Also, if you want a doughnut, have a doughnut and don't feel bad about it. You shouldn't try burning it off through intense exercises.
