Physical activity is a useful tool for preventing and easing depressio
n symptoms. When prescribing exercise as an adjunct to medication and
psychotherapy the complexity and the individual circumstances of each
patient must be considered. Hopelessness and fatigue can make physical
exertion difficult, and some patients are vulnerable to guilt and sel
f-blame if they fail to carry out a regimen. A feasible, flexible, and
pleasurable program has the best chance for success. Walking-alone or
in a group-is often a good option.
