I don't need a scientific paper to tell me that exercise helps depression. I wouldn't be here if it wasn't for exercise. That's not to say it'll work equally well for everyone, but there's enough empirical evidence to suggest that it's one of the best tools available. That said, every doctor I've ever visited (except one), recommended exercise as part of their treatment.
