Everyone needs to do exercise because it has a range of important side effects. The evidence for exercise as a treatment for mental ill health is not good. It's really hard to disentangle the effect of any form of "activation" (this doesn't have to be exercise, it could be joining a book reading club) from the benefits gained through exercise. We know it can be difficult for people to start and then maintain an exercise regime, and this failure to stick to it can cause some people to feel bad about the failure.
