> What happens when a depressed person forces themselves to do things that are associated with not being depressed?
Well, the problem is that depression causes a lack of motivation, and the lack of action or inability to do even normal chores continues to fuel the depression. (Depending on its severity it sometimes even impairs people from doing basic tasks like taking care of personal hygiene - there are cases where indiviuals don't brush their teeth or even bathe for weeks; e.g. https://web.archive.org/web/20120305002714/http://damnihateb... ). So to us "normal" individuals these people may look lazy or those that lack discipline, but it's actualy the disease impairing them.
As you guessed though, taking actions is indeed one of the behavioural techniques of Behaviour Therapy or Cognitive Therapy to tackle depression. It does work, and depressed individuals do cite an improvement in their mood when they do some task (especially stuff they have been procrastinating).
But if you consider the cognitive model of depression (i.e. the common thinking patterns of depressed individual), one other aspect of depression is that they don't feel satisfaction or a feeling of accomplishment in doing such tasks. And thus, any mood improvment is only temporary. Which again makes them feel helpless and they regress. Thus, cognitive therapy focuses on not only encouraging behavioural actions, but also working on correcting thought patterns that devalue such actions.
("Perfectionism" is one example of such thought pattern - if something is not "perfect", the individual often devalues the whole work done. Using the same examples you cited, even if you get this kind of individual to do a workout, as soon as s/he misses a workout, they will immediately start to blame themslelves for not being able to "maintain" discipline to the point of becoming dysfunctional..
